Hitler was fanatical and ideologically driven (as many people and political leaders are) but he wasn’t mentally ill. To answer your question if Hitler didn’t take charge of Germany in 1933 for one reason or another there certainly wouldn’t have been as large of a war or anywhere near as many atrocities. Hitler didn’t magically do this all by himself of course. He had Himmler, Goering, Goebbels etc along with the support of the majority of the German population and the Wehrmacht but it’s hard to imagine a regime as evil and conquest obsessed as Nazi Germany taking control if Hitler and the Nazi Party faded into obscurity for one reason or another. Very few political entities have come close to the Third Reich in terms of scope, scale, ideology and intent.Hitler has occurred to me to be uniquely crazy.
I think you are near the mark. A smarter leader of an authoritarian and openly antisemitic regime could pursue similar goals in terms of rearmanent and regaining lost German lands. Possibly with a better economic and diplomatic performance.The post war settlement was unique and fundamentally flawed. It was a peace made against the two great powers of central and Eastern Europe, Germany and Russia. It was inevitable that one or both would recover in whatever political form they took, and would challenge the post war settlement. A non Hitler less racist regime such as a more authoritarian nationalist or monarchist regime may still pursue similar ambitions and therefore war against its neighbours, leading to another world war.
Problem with that is Versailles was being undone well before Hitler, WWII was the product of Hitler's obsessions and I seriously doubt any other authoritarian regime would have been so reckless.The post war settlement was unique and fundamentally flawed.

Post 1918 Germany like 1871 France wanted revenge
As @Mikestone8 pointed out the German public were depressed by the prospect of war in 1938 and every bit as elated by the Munich Agreement as the British public. In the aftermath of Munich many senior figures in Germany were declaring that it was time for a period of consolidation and to rebalance the economy to boost the civilian sector and export industries. Only Adolf Hitler was disappointed that war hadn't come and in 1939 there was no political or economic reason for Germany to go to war outside of Hitler's warped world view. Had Germany stuck to its promises after Munich there would have been no war.Post 1918 Germany like 1871 France wanted revenge
Just the minor issue that the unsteady and mismanaged Nazi economy required looting to sustain and most people in power wanted a strong military.As @Mikestone8 pointed out the German public were depressed by the prospect of war in 1938 and every bit as elated by the Munich Agreement as the British public.

Not so much in 1938, the very same people who had been willing to go along with expedients like MEFO bills to finance rearmament and felt that it was imperative to restore some semblance of financial normality while they still could. Now Germany might have been heading for an economic crisis either way but they certainly weren't in favour of any military adventures that would just make matters worse.Just the minor issue that the unsteady and mismanaged Nazi economy required looting to sustain and most people in power wanted a strong military.
And they were promptly shown the door in a display of how little power they had. 1938 was when they had to pay in cash, so they choose the dumb plan of exports to earn cash and still breakneck military production.Not so much in 1938, the very same people who had been willing to go along with expedients like MEFO bills to finance rearmament and felt that it was imperative to restore some semblance of financial normality while they still could.

While it is true that the people (besides Hitler) who realized that rearmament would be economically ruinous in a few years time and advocated for rearmament to be scaled back were either sidelined or canned, that doesn't mean the remaining German leadership (again, besides Hitler) regarded going to war as a prudent measure. Most in the Nazi Hierarchy and the Wehrmacht leadership wanted to take Munich as the final triumph in the restoration of German greatness and cash in. Embarking on a war was not a gamble they were willing to make without a charismatic leader utterly devoted too it leading them into it by the nose as Hitler did.And they were promptly shown the door in a display of how little power they had. 1938 was when they had to pay in cash, so they choose the dumb plan of exports to earn cash and still breakneck military production.
