Earlier quoted context omitted.
All innovation is composition plus random generation. Which LLMs already do. LLMs have a rudimentary form of innovation. It's not quite as good as humans but it's getting there.
Innovation isn't just testing something new, it is a new thing that improves something or is valuable in some way. So doing random combinations of things isn't innovation, it is just noise.
Again I like to emphasize that it's not "truly random" we can't even define randomness formally with a function so this doesn't exist. It's more of a combinatorics algorithm where we iterate through every possible and likely permutation.
