This is a problem of insufficient checking happening in-between a PR being made, and it being committed. Imagine you have a low quality coder in your coders, they produce a lot of code, but while some of it is fine, some of it is... dubious. That is no different from an AI and the way you deal with it is the same. You check the PR before committing it. To allow PRs from them (or anyone really) to get merged without proper checking for bugs etc is just sloppy repo management. The problem is not "AI bad, human good", it is that a human is allowing PRs through to release without properly checking them.
