Does God learn and grow from our mistakes as well as our creations?

This is very much true. And the reason again is that you are not simply atoms and molecules interacting according to the laws of physics and staying within those boundaries, which are all predictable in the potential outcomes. Even with total randomness and an uncountable number of particles and quantum bits of energy, there are still many predictable consequences, and the probabilities will come into play as well, to make some things much more likely than others. But what you do as creators is to make a quantum leap in a real and true sense, to leap beyond the boundaries of what came before, to make something novel that does not proceed in a linear fashion from prior experience and therefore has great novelty, and the delights of representing a surprise even to us at times. And again, this is not because we were unable to conceive of it, but simply had not done so. This is true for human surprise as well. Most things that happen that are unusual and unexpected are at once understood, but, were simply never contemplated heretofore. They are novel and a delight for that reason. This is a divine and divinely shared characteristic.
