Because if you made an integrated chip with an I2C interface that claimed
to produce random numbers, nobody in this community would trust it!

And anything that shipped in high volume would just integrate the
random number circuitry into a VLSI chip (as modern CPUs have done),
rather than using even a tiny extra chip and the wires to talk to it.
