There are no discrete chips, but plenty of devices like USB keys built up from
COTS parts.  Just google "open source rng" for examples.

They wanted nearly half a million dollars funding to create something that you
can buy now for a few tens of dollars.

The problem isn't that there aren't any available, it's that when it comes to
trying to secure the Internet, a hardware source of random numbers, whether
it's open-source, closed-source, single-chip, discrete-parts, or anything
else, is pretty much irrelevant as a solution.
