Some people just want their name in the contributor list, whether it's for ego, to build a portfolio, etc. I think that's what it comes down to. Many projects, especially high profile ones, have to deal with low effort contributions - correcting spelling mistakes, reformatting code, etc. It's been going on for a long time. The Linux contributor guidelines - probably a lot of other projects too - specifically call this stuff out and caution people not to do it lest they suffer the wrath of the LKML. AI coding tools open up all kinds of new possibilities for these types of contributors, but it's not AI that's the problem.
