I guess I have no problem in theory with AI agents taking a look at my code it’s just I would want it opt in only. I don’t want to have to deal with them on legacy projects that I’m not working on, or anything mission critical (if there is a bug in the code but the application overall still works, I’d rather not have an AI dick around with it until I have time to properly go through it).

To be clear, I would have the same objections to a human doing the same things. It’s just that most humans don’t randomly submit pull requests on otherwise inactive repos.
