PS: The Tetris movie is coming out soon :)
Umm, no it can't. I understand your general question, but ChatGPT isn't capable of creating a finished, graphical game that looks like Tetris in "a single response". It would take many interactions, refining, correcting and adding to the queries, maybe.
But even if ChatGPT could produce something that the Tetris people would be concerned about, they wouldn't sue ChatGPT but the ones offering the code (free or otherwise) to others. So the legal situation is pretty much unchanged.
