LLMs are essentially unregulated. I don't believe they have any legal disclosure obligation in America.

They may ignore the disclosure obligation, but technically they are supposed to disclose this fact.

They'd show it regardless (maybe as a popup though): the disclosure doesn't make it that much less effective at scale, and the optics of getting caught vs just disclosing it are not worth getting dragged into
