In theory, I don't see any particular reason for AI-generated ads to be specially labeled as such. But two rules I would suggest:

- If ads, products, or whatever claim to be AI-free, then the penalties for the claim being untrue are pretty severe.

- "The AI goofed" excuses - whether in advertising claims, support chatbot responses, employment decisions, or whatever - will get the same legal consideration as "the unsupervised illiterates in our Packaging Dept. swapped the labels between the baby formula and the rat poison yet again" excuses.
