I can totally see the appeal of using LLMs to _help_ the DM. Not to replace it.

I DM a few games of The Expanse, and using LLMs to plan ahead was a godsend. No, I didn't utilise it to write the story for me - instead I used it to test my planned story and see which way my players might strafe off the road, so I can plan for those. Basically simulated a game using an LLM that acted in place of multiple characters, allowed those to run free (within certain limits, obviously you can't have the LLM players do a dozen actions without the DM having a say), and essentially mapped the potential "off branches", story pathways I didn't plan for initially. This has allowed me to be prepared for the usual dumbass things players might do, such as heading for a strip club in the middle of a total disaster where they (figuratively) have dozens of arrows pointing to the goal of the chapter.

Another interesting aspect of using AI for TTRPGs is to create atmospherics. For Expanse based games, I've bought a number of tile packs and such, to appreciate the artists who put work into it, but I simply don't have the funds to commission a few dozen acrylic matte style scenery images (which I usually put up on my projector, combined with some Hue lights to create the visual atmosphere). With AI, I can even generate them on the fly, should my little gremlins stray off the path. Same for music - AI can incredibly easily generate an atmospheric soundtrack that fits the current scenery, with just a few words, while I can still pay attention to the players.

But fully replacing the DM? That's silly.
