LLMs are really bad at this. I tried finding long lost comic book using everything available on the market and got either basic bitch replies listing biggest authors and suggesting its in one of their works or plain hallucinations.

Doesn't have to be LLMs specifically. With how much data and metadata major companies have on all this media, it shouldn't be impossible to do this sort of stuff. But it's probably not mega-profitable enough. They'll just keep shifting buttons on devices and maybe rounding some corners on UI buttons.

EDIT: Maybe LLMs trained on the media itself - cast, crew, physical descriptions of people and places and equipment in various scenes, along with timestamps... - maybe LLMs and other search tech together could do this.

I was recently hunting down an 80s TV episode with a particular supporting actor. ChatGPT confidently lied about the actor's name despite it being in many data sources.

Seconded. ChatGPT is terrible at saying "I don't know".

And Elon says they have run out of training data ...
