>>58750299After you catch Rayquaza, all the teams update and Korrina's added to the pool, yes.
In general, everyone just gets level bumps to the 80-96 range, but Taunie/Urbain gets a massive upgrade to a team of all 100s with Mega Meowstic, Avalugg, Mega Manectric and their Mega Starters.
Korrina just straight up runs a full team of Mega Fighting Types in the late 90's, with Lucario Z at 100.
Emma now uses Mega Lucario in addition to Mega Malamar.
Lida now uses Tatsugiri and Naveen now uses Lowkey Toxtricity, synchronizing with their final sidequest battles.
They didn't give much a shit about the sub-leaders though, they're still running five Pokemon despite there being plenty of worthy sixth additions and the fact they've been fucking around Hyperspace just as much as anyone else.
