First off all, it’s a legitimate way. He just goes through the install instructions from here (https://github.com/termux/termux-x11).
The one thing I would do differently is choosing the right package for your architecture or going with the universal package instead of the arm64 package as he proposes.
Lastly I want to add that that depending on what you want to do a graphical session is sometimes not necessary. Example: For tools like mov-cli for watching movie in the terminal, termux alone is enough, because they integrate with the android mpv app and don’t need a xorg session to display graphics.

I hope I understand correctly what you mean. Lika a text based adventure game but instead of fixed options you write your action and the AI reacts to it.
So a developer could write his own LLM Model and define a setting on what he trains it and then the player have a text based adventure. The game dev has set the story but he player can write his own actions instead of using the predefined ones. The LLM then reacts to them so there is more dynamic in the game.
Is that what you mean for example? If so I would say that is a use case with the limitation that simply using chatgpt or similar would defeat the use case because it is a to general model.
