There's no "LLM style". There's "human style mimicked by LLMs". If they default to a specific style, then that's on the human user who chooses to go with it, or, likely, doesn't care. They could just as well make it output text in the style of Shakespeare or a pirate, eschew emojis and bulleted lists, etc.
If you're finding yourself influenced by LLMs—don't be. Here's why:
• It doesn't matter.
• Keep whatever style you had before LLMs.
