Not sure why that's contorting, a markov model is anything where you know the probability of going from state A to state B. The state can be anything. When it's text generation the state is previous text to text with an extra character, which is true for both LLMs and oldschool n-gram markov models.

Well LLMs aren't human brains, unless you contort the definition of matrix algebra so much you could even include them.
