For getting ideas on variations of short phrases and basic sentences, there might be some applicability, but anything beyond that usually runs into huge issues of style and consistency that requires re-writes and corrections so frequent that it would probably end up taking more work than the author just sitting down and doing it naturally in their own words to begin with. I've tried enough other text-based games to know how important consistent and high quality writing is, and I'm not terribly keen on the idea of polluting DoL with random machine-generated drivel. But garbage input leads to garbage output: if you can train an "AI" (language model) on only the writing of DoL, maybe it could take a bigger share of the workload with less errors and issues that would need to be corrected. Though I take a certain comfort in knowing that an actual human wrote something with both deliberation and purpose, especially when it comes to something like DoL that is written in such a particular style and with clear intent behind its words. I can't imagine the author of the game would ever feel comfortable with it given the marvellously detailed-oriented and perhaps even obsessive compulsive quality control they've exercised thus far, but who knows.
