I've been using LLA for years with cast bullets, but I've never tried it with jacketed. I guess you'd coat the bullets before you loaded them, but I'd be interested to see how much scrapes off during the bullet seating process. With cast bullets we flare the mouth of the case so that we won't scrape the lead. However, the three bands on a Barnes TTX might hold lube just fine.
I'm not saying it's a good idea, just war-gaming the possibilities.
