Indeed. Even before LLMs you could hire a cheap ghostwriter on upwork. Or even better, hire one to write the outline, another to flesh out the outline into a book, and a third to proof it. Get a cover on fiverr and upload. Then rinse and repeat. Fiction, nonfiction, doesn't matter. Whatever sells. Amazon's KDP program had to institute (very modest) upload limits for this reason. People were turning capital into a deluge of slop books -- hundreds per day in some cases. As usual, the real money is in selling courses that "teach" people how to do this technique.
