I'm tired and drunk but I don't want to forget to respond to you, I hope to give you a better response at anotehr time.
For now I will say that:
Indeterminism implies literally that we "could have done otherwise" but as I said above it also implies that we cannot determine ourselves and therefore can't will ourselves. "could have done otherwise" is more than just the literal meaning, it means "could have done otherwise using ones own will, could have willed it the way we chose it to be willed", the kind of "could have done otherwise" in indeterminism is the same kind of "could have done otherwise" that a bunch of dice or a roulette real has, that's not free will.
