Pedantic warning here. In fast and loose day-to-day common English language "exponentially more" means "fast growth" or "a whole lot". But that usage is meaningless! Why?, technically, you can't have exponential growth without a dependent variable. You can have exponential growth as a function of time, height, spend, distance, any freaking metric or variable. But it has to be as a function of a value.

You CAN'T have exponential growth that is not a function of some value or variable or input.

I suppose in this case you could argue you have exponential growth as a function of the discrete using-an-LLM or not-using-an-LLM, but I've never heard of exponential growth as a function of a discrete.

Often people using the term "exponential growth" in common English don't understand what it means. Sorry.
