Why would you consider using lists an "LLM" language thing? I really don't understand this concept. Like even this project, the top words I can see are:
1. load-bearing 2. plainly 3. quietly 4. refusal 5. survived
How are they LLM words? I used them all the time before ChatGPT was a thing.
Like if your claim is you use "etc." more because you talk to an LLM, I think you're just discovering human language, no? Like it's not a unique LLM thing that magically dropped and is now going to make people do it. It's a legit thing that most human writers have used for a long time -> which is why LLMs copy it. It's not backward.
A better claim than "people will start writing like LLMs" could be that people will become more literate in expressing themselves. But that literacy is not alien or AI to us, it is basic human language only used properly.
