For anything like this, I don’t understand trying to invoke AI. Just open the file and delete the lines yourself. What is AI going to do here for you?
It’s like you are relying 100% on AI when it’s a tool in your toolset.
Playing devils advocate here, it's because removing a function is not always as simple as deleting the lines. Sometimes there are references to that function that you forgot about that the LLM will notice and automatically update for you. Depending on your prompt it will also go find other references outside of the single file and remove those as well. Another possibility is that people are just becoming used to interacting with their codebase through the "chat" interface and directing the LLM to do things so that behavior carries over into all interactions, even perceived "simple" ones.
I like to code with an LLMs help making iterative changes. First do this, then once that code is a good place, then do this, etc. If I ask it to make one change, I want it to make one change only.
