I would use the coin, dice, whatever to get the binary entropy itself
to then convert that binary entropy into base10 and search the word from the wordlist for every 11 bits
you basically used the dice to directly get the words (which are converted binary bits)
using dice to get individual entropy bits could be waay more random (you pick every part of the 11bits per word individually, instead of just a few individual whole words..)
