Why not fighting fire with fire and using AI to:

Version A: find 100 LOC which can be reduced to 50 LOC without changing the functionality. Then ask the author to go through the PR making sure it's not bloated. Repeat.

Version B: find hidden bugs. Ask the author to fix them. Repeat.

Keep them occupied saving your face. I would also fine tune an own agent to automatise this kind of work for me.
