It's interesting that he'd go out of his way to point out where one slave of many supposedly lived.

There’s no indication that he [the grandson Randolph] went “out of his way” to lead Randall to that spot. Rather they were walking through Monticello (”Walking about mouldering Monticello one day”) when he pointed it out.
Obviously the topic was of special interest, though — accusations against Jefferson having been publicized widely during early political campaigns — and Randolph used the occasion to tell Randall a few things about it.
You’ve posted quotations about closets associated with storage near Jefferson’s bed, but I’ve seen nothing about Sally having lived there (and would be stunned to see proof that she did). Randolph, on the other hand, provides testimony — from a person who at the time when Sally’s children were born there “had charge of Monticello” — that Sally’s room was “in one of the collonades [modern spelling “colonnades”]”. He also provides significant testimony about the conduct of Thomas and other persons while he was living there.
