Exactly. If determinism is incompatible with somebody's personal meaning of free will, quantum dice rolls are hardly a solution. What they really need is to either find a religion or just shrug off philosophy and get on with their life, behaving as if they have free will even if they can't rationally justify it.
Quantum dice roll is _the free will_ in this context. So your free will is what sets the dice; as it is extraphysical, it will look like randomness in the physical world.
