Is it legal to sell AI-generated art on Etsy?

I'm curious to know, is the act of selling art that has been created by artificial intelligence (AI) platforms considered legal on Etsy, a popular e-commerce website for handmade and vintage items? Does Etsy have any policies or guidelines in place specifically addressing the sale of AI-generated art? Additionally, are there any legal implications or considerations for both the seller and buyer when it comes to the ownership, authenticity, and potential copyright issues surrounding such artwork?
