I don’t want to generate the randomness myself, though. I want a physical tool that doesn’t rely on a pseudorandom number generator that may or may not have a vulnerability exposed in the future.
See here for an example that illustrates my concern. It took 7 years to find the vulnerability.

Tin foil hat approach, but I get it.
For the rest of the planet, entropy sources should be combined. e.g. Trezor seed generation mixes host provided entropy and the on device TRNG.

I appreciate your feedback.
