I can't think of any use case for this that you can't already get with hardware random number generators that computers have built-in. For most people TRNG's are only useful for things like generating keys and such, something that not much entropy is needed for. Typing in random letters and hashing them would suffice.
Typing in random letters and hashing them would suffice.
That seems pretty iffy to me. Humans are really bad at generating randomness, and the entropy from "randomly" typing letters is going to be far less than you think. It's better to go with hard drive and network latency, or the least significant bits of keypress times, which are far noisier than which keys were pressed.
