Turns out: even though only the RNC-Id is sent in the id-Reset message, both the RNC-Id *and* the LAC are transmitted in an InitialUE message.
For the record, see the RANAP spec (3GPP TS 25.413 version 12.4.0 Release 12) chapter 9.1.33, which lists all of Global RNC-ID, LAI and SAI IEs as mandatory, where both LAI and SAI include the LAC, also mandatorily.
It's interesting how LAI and SAI are mostly redundant, yet both are mandatory.
