Exactly my point that it is not clear, since it’s exactly Carlin’s likeness. A person who tunes in at a random moment has no idea that this is what it it stated in the beginning and could 100% assume it’s Carlin.

It is incredibly clear. The fact that it would take a person to pause the video before the first three seconds, skip to a random point, ignore that the topic of the standup is events that occurred since his death and being an AI, fail to read the written notices on-screen and in the description, etc. is evidence of this.

using their exact likeness as a basis is not transformative work

I think you’re still getting wires crossed between different domains of IP law in a way that makes your objection meaningless. Transformative nature comes in as a part of a fair use defense specifically to copyright infringement - whereas elements of a person’s likeness, like their face or voice, are not protected by copyright.
