I can never fully embrace LLMs for code

My younger sister graduated with a CompSci degree a few years ago. I've been behind her, motivating her and demystifying the world of programming from the very beginning. There was a piece of advice I repeated everyday, trying to make her understand how to operate. The problem was, she was trying to read and understand every line of code in a function before using it. I thought it was non-sense. Someone, much smarter than us has created that function, it's part of a vetted library, it has been tested already. All you have to do is use it. "After all, you don't need to understand how an internal combustion engine works, yet you feel safe driving your car, don't you?" Now, I find myself right at that inflection point.
