I am then feeding $ci, $tt, and $ft into dlg_get and then calling dlg_bye("all") - in which Kamailio then proceeds to send BYE out to both legs of the call.

Contrary, using certain dialog features (including dlg_bye()) from reply routes isn't completely possible yet which could explain your findings.

An idea I have what you could possibly be doing wrong is not using the CSeq numbers that each party expects. I don't have the details at hand but if either CSeq number is off your UAs won't accept the BYE request.
