How to report content that is clearly AI generated, but isn't labeled as such?

Same. I reported those AI packs which participate in the 70% Holiday sale and are labeled as NOT made with AI.

I wrote the US and EU laws that require labeling AI-generated content.
1 minute(!) later, my reports were closed with:
“No Action Taken
After a thorough review, we determined that the content reported does not violate Epic’s rules or any laws.”

They even state: “Repeatedly falsely reporting illegal content may have serious consequences, up to and including a permanent account ban.”

The AI which does FAB content moderation is permitting illegal content to be sold and bans trustworthy, legit sellers for nonsensical, made up reasons while users that want a transparent and legal FAB are being threatened with account bans.
