Are you suggesting that workers are NOT already more constantly "on the clock" with mobile phones/email/slack/text than before those things?

(I'm not really sure LLMs will make it that much worse here, but all those things have been harmful to workers already.)

Well yes, they did... For example: https://news.ycombinator.com/item?id=29201917

And yet it is still possible to maintain work-life balance, given the right job at the right business, even after the invention of email.

Remember "Crackberry"?
