The difference is huge. Put yourself in the shoes of a student.
The student you're copying from won't be sitting next to you for the rest of your career. The LLM probably will be, and you'll be probably expected to use it, so why not use it here as well?
All your peers are doing it too, and look at all the cool things they're doing while you're struggling with the basics. And what if the LLMs keep improving at a high rate? What if being able to use them efficiently turns out to be a more important skill than what you're being taught anyways?
