Sorry for the double post but I went though the text dump (Man all the mid battle unique dialogue is just pumped into one text file...) and found where the Battle Prep, Level up/Class learning, and non-unique mid battle voice lines are. Starting from file 891 for the Battle Prep and Level up/Class learning lines, and 1008 for the mid battle lines. 1054 is where I noticed the NPCs starting to appear, and like the Player units, their lines are in the same places as them so you can get a general idea of what line is used for what context like taking over a stronghold or praising a Ally.
