I'm in two minds on how best to handle these kind of, "but you have to use an LLM" issues. In my heart I'm like you; they hired me to do a job. If I'm doing the job at the rate and quality expected, why should they care if I use an LLM, my brain, or randomly throw mud at the keyboard until something magically works? The practical side of me says, "I like a roof over my head" so if they mandate I have to use an LLM then I'll do it as long as they take responsibility for any negative impact from that decision.
