How about #HumanMadeWithoutAI or just #MadeWithoutAI? I feel it needs to be more specific than #HumanMade since that is a fine line of did a human make it and use AI or not.

A little bit long: #NotMadeWithAI
#MadeWithoutAI

shorter:
#NotAIArt
#RealArtist

politically incorrect:
#SuckAI
#NoFuckingAI
#DontTalkMeAboutShittyAI
#DidYourMotherNeededAnAIToBePregnantWithYou
#NotAnAICounterfeit
#ThinkWithYourBrainNotWithAnAI
