I feel the same and I experience less pressure when writing because for the first time it seems being a bit sloppy can be advantageous.
The only thing is that my anecdata contradicts it. My AI cleaned up writing seems to fare much better and this seems to be true across all channels. To be clear I do not mean AI generated just AI cleaned, that is spelling, punctuation, grammar mainly, the occasional word order change.
In the end it's about getting the message across first and "get to know me" second and proper and clear expression helps a lot with the first.
The level of AI use you're describing isn't what people are complaining about (and probably don't even notice). Fixing grammar and occasional word order change isn't going to make your entire article sound like insincere bullshit.

All of those you could already achieve with tools before LLMs.
