I'm not sure of the situation in France, but this is starting to happen readily on Amazon. Lots of physical books you can buy that are completely AI-generated nonsense.
Many people argue this is bad and should be changed. But it's debatable.
What scares me is that some mixed works (PDF/on-demand prints) are not archived because the authors think the system is too clunky to deal with, which is really a shame for books like https://laurent.claessens-donadello.eu/pdf/lefrido.pdf, for example.
