> It's like half the people have turned off their brain.

LLMs are for people who want to turn off their brain. If you want your team to improve, you should lead by example and stop using LLMs. You need to create an environment where it is unacceptable to turn off your brain. Your underlings will never use LLM tools the way you want them to. LLM tools are designed to be used the way your underlings use them.
