Is it possible for such a system to actually generate a random output without explicitly stochastic mechanisms?
If your idea of an explicitly stochastic mechanism is something like a pseudo random number generator, then it’s possible , but complex, and so unlikely compared to the much easier alternative of using some kind of existing noise, IE failing to perfectly filter out noise.
