The short answer is appears so but i would personally avoid their devices entirely for the time being.

if you're going to re-use and existing device i would then upgrade the firmware and then use dice roll.

Since the problem is the TRNG source failure, then it is better generating keys using offline desktops. I would not trust limited hardware/software at this moment...

no, only physical dice

100+ fair rolls should give you the same seed and security as other comparable devices for this task, like SeedSigner.
