I don't think I've ever had problems with Latias/Latios. For what I know (i.e. if I were using that team today), I most likely would Twave. Then switch if it used Trick (likely switching to Volcarona). If it used Draco Meteor instead, I'd just let my puppy faint and either Volcarona or Dragonite will be at to set up after Lati@s gets itself to -4 and then -6. If it tricks and I switched to Volcarona, then I think I probably try to set up with Volcarona (sub first). Lati@s really can't do anything scary to Volcarona (other than KOing is I mean, as in... it cannot set up because it has no set up moves). If Volcarona faints, then I get Stoutland back in to Sand Attack, and when opponent has run out of Draco Meteor PPs (or when Stoutland faints). I switch back in Dragonite to set up. Alternatively, I do it the other way, let Dragonite faint to have Volcarona set up. Volcarona would be easier to safer to set up here, just because of QD's increasing Sp Def and also Rest not caring about potential Tbolt paralyses from switching in. This is pretty much the same with all Trick pokemon I think. Always Twave if opponent is faster. If I get locked into a move, then switch and try to get Stoutland back in to either Charm (Physical Attacker) or Snarl/Sand Attack (Special Attacker). I opponent is somehow not even faster than Stoutland with a choice item, then still Twave, followed by locking yourself into Charm/Snarl/Sand Attack... so that's even better not having to be locked into Twave of course. You are correct about Sand Attack though. If I do not know whether opponent is physical or special, after Twave, I would usually sand attack. I think there are some exceptions like Dragonite, where I'd always charm regardless, just because the special version is not hard to deal with at all (whereas the CB one is annoying). I think I had much bigger problems with Rampardos than Lati@s with this team, especially the Choice Scarf one, where it kills itself with Head Smash and thus would never allow Dragonite to set up more than a +3/+3 or so (more likely a +2/+2 or so I think). I Twave, Charm, faint, and then Dragonite Subs til Rampardos loses the last Head Smash PPs, and then set up on struggles, but only 1 or 2 struggles to work off of because of Head Smash recoils... eek.
