You could book with AA, by calling their RTW desk, which uses a U.S. PoS. You'd still pay the ex-U.K. price since that's where you're starting. It might work to call the U.S. BA line; you could always call them and ask if they see L inventory on that flight on your date. You could also book it with a dummy date for that flight (and possibly everything after), then later call and have the dates changed, since that is free.
My suggestion is to either call AA or call the U.S. BA number and if they can see the inventory, have them book it. If AA books it, they can price it in GBP.
