I think we want (and expect) RNGs to produce sequences with high algorithmic complexity (which we regard as "random") and ignore the (almost impossible) possibility that they fail to do so. An impossible to create modified RNG which always produces sequences with high algorithmic complexity would better meet our expectations of randomness, but would be less random because it could not produce uniform sequences (among others).
