You may want to stay away from all modern CSPRNGs then. Eg Yarrow and Fortuna rely on sources of random input data being mixed in but using a strong hash function (nowadays sha-256) to produce the output at arbitrarily fast rates without consuming entropy.

And to your criticism that this is just programmers who don’t know what they’re doing, these algorithms were developed by Bruce Schneier, Niels Ferguson, and John Kelsey.
