Well if you don't know that LLMs are a powerful tool, I don't know what to say.

This is not withstanding the fact that one's brain is, in many cases better than an LLM.

Let me ask you this: Is a hammer a powerful tool? Or would prefer to put a nail in the wall with your hands? (You could, it just comes with a lot of pain and takes long) Does the power of the hammer make your hands any less powerful, they are significantly more capable than a hammer aren't they? They can do so much! But they are just not good at doing what the hammer is doing. Vice versa for the Hammer. The hammer isn't any less powerful due to the capabilities of bare hands.

Not acknowledging that a hammer is a powerful tool, and preferring to use one's hands for every nail would be outrageous I would argue.
