It's an adversarial economy. Using a LLM at work doesn't mean the work is challenging. A lot of jobs are "bullshit jobs". People are using LLMs because it gives them back time. If they don't use it their colleague will and make them look bad.
Company might fire you tomorrow. Fundamentally if a LLM can do the job it's not just employees at risk, it is also the company. There is a lot of symmetry actually with how companies delegate to employees to how employees delegate to LLMs. You can follow the logic to conclude a lot of companies are then bullshit companies. This is not a problem for the individual to solve. Your job at work is akin to the company's - earn the best return while you still can. Wasting your time for the essentially the same output at a slower pace is a bad return.
When people get laid off en masse this incentive structure will have to be altered. But telling an individual to ignore their basic economic incentives until then is unlikely to work.
