I am most certainly not waving hands and saying that review is enough

Apologies, that's what it sounded like to me. You said it's clickbait. You said the title would work without AI in the title. You also said that AI generation isn't relevant. That felt like diminishing the conversation - focusing in on what you're most concerned about, and dismissing all other discussions. I don't think that helps discussion happen. It discourages it. It says that we shouldn't talk about the problems present here which exist outside the realm of just the review process.

For example, both of the figures do have a description, but neither of them have any kind of attribution. The review process might ensure it is factual when it is followed and still let through material such as that you've laid out above which do not involve AI - like hiring someone off of fiverr. One way to solve this would be with image attribution. As I mentioned above, simply requiring that an image explain where it came from, such as requiring attribution to the artist who created the figure or requiring that the software used be attributed (perhaps even requiring the full prompt for generated images) are all methods through which we can ensure scientific rigor (and accurate attribution) which will both help ensure the review process catches problematic material and cues the readers in to key information about the figures present in research.
