There are 4 seats in F on the AA DFW-LHR nonstop on 4/30/22 for 85k plus $5.60 each. It doesn't sound like you have a good way to get the 170k AA too quickly but if you did, that's a pretty good option...
You could sign up for a couple of AA cards (1 personal and 1 business if there are still good offers out there), then transfer Marriott over to AA (not a good transfer rate but not terrible for just a top up).
