I have a more straightforward rebuttal of the need for an AI Hemingway. Someone already implemented a decent interactive guide to writing like Hemingway at least a decade ago, before all this LLM stuff: https://hemingwayapp.com/

It uses some simple heuristics to identify grammar that could be simpler and prompts you to do better. It might actually be better than an LLM specifically because it isn't able to do the rewriting for you. Maybe that might help a user learn.
