They will undoubtedly want to make repairs, but with resource and manpower limits starting to bite there may well be choices to make.I wonder if the Germans would actually bother to repair their damaged ships?
This little escapade will have probably convinced them of the stratigic impotence of the high seas fleet.
Hindenburg and Lutzow have probably only taken light/superficial damage and so can return to service quickly with the minimum of effort. Possibly the same with Seydlitz just taking longer.
The big problems are Kronprinz and Moltke which would likely need to be dry docked for many weeks for extensive work.
The German government may decide that it is unlikely that the High Seas Fleet will sortie again and that the resources (especially steel) needed for repairs would be better being allocated to building more U Boats or artillery pieces for the army and the like.
In the case of Moltke given she is now likely a mess of repair jobs it wouldn't be surprising to perhaps see her scrapped with her crew plugging gaps elsewhere and the recovered steel perhaps used to finish off newer ships.
U-boat production has ramped up (a bit less than OTL, but still up), so there are limits on what is available for the surface fleet. They've already effectively suspended new construction.
Hindenburg, Lutzow and Kronprinz are among the best ships in the fleet, and as you say the first two are not badly damaged. A little effort with Seydlitz gives them a four-ship BC force (they also have Von der Tann undamaged).
Then, they might choose to 'bodge' ships, keeping them operational, but not necessarily in ideal condition - e.g. plating over missing guns/equipment rather than repairing it, or filling voids with concrete/wood simply to make them watertight and provide a smooth-ish hull.
Moltke almost certainly fits that condition.
