Why? In the end it's a patch's quality that counts. Regardless who or what contributed it.
Bad patch from trusted contributor is still a bad patch.
Perhaps this is more a management problem. How to best use developer's time, where to use AI (vs blindly deploy AI to generate patches & swamp developers with that).
Or do some rate-limiting? "Sorry, we accept no more than 10KB worth of patches per week on this project! Try again next week after we've reviewed this week's batch".
