So extant memers of Rhyncophthirina are ectoparasites of large,

Don't know, but it sounds like the Rhyncophthirina might spend a lot of time reminiscing about the good old days.

Is the allometry of skin thickness in extant animals known well enough to speculate about details of the mouth parts required to parasitize a sauropod?

Certainly cowhide is thicker than rabbit-skin, but as a function of volume, I intuitively expect cowhide to be relatively thinner...
