I’ve seen from customers selecting entropy sources is the speed of ‘built-in’ entropy sources, to the point where they will actively look for faster ones and pay quite a bit more when they do genuinely need them. The market is there.
Sure and customers buy Monster cables because they've been told they sound better. I'm sure there's a market, but exactly what is this genuine need and do they really understand their own problem? Also for more than a decade now modern systems have a fast entropy source with on chip RNG such as RDRAND and this extends to the embedded context.

Unfortunately, my information stops at the fact that they claim to need the high-output entropy source.

On-chip RNGs are useful, yes, and are often enough for most use cases. In particular, I like Intel’s RDSEED quite a bit, but the larger (in terms of core count) the chips have gotten, the more convoluted the distribution network for the material has become. Even still, the speed of RDSEED (note, RDRAND is an automatically reseeded DRBG, whereas RDSEED is an RBG3 XOR construction (as defined in SP 800-90C) which has fresh entropy in each output) has fallen to a rate in which some vendors are looking for something faster.
