All of this is completely irrelevant to the question of local causality within the context of Bell's theorem. Bell mathematically formalized Einstein's conception of local causality in his 1964 paper by defining local functions of the form A(a, h) and B(b, h), where a and b are experimental parameters, freely chosen by Alice and Bob, and "h" is shared randomness between them.
The correlations between the results A(a, h) and B(b, h) observed by Alice and Bob are then computed as E(a, b) = (1/n) Sum_i A(a, h_i) B(b, h_i) = -cos(a, b). All the rest is irrelevant.
