The OP is flying BOS-LHR with an 85 minute connection to the last flight of the day out of LHR. I think it's a fair conclusion that they're on AA156 which gets in at 8:30pm not AA108 which gets in at 6:35am. In that case it's likely that there is not an earlier flight out of BOS (AA156 departs at 9:00am). The original post stated that there isn't a later connecting flight.
I don't know what BA/AA would do vis-a-vis hotel on a OW180F, but I've got a 5 pound note that says the OP won't make an 85 minute terminal change connection at LHR. I'm a little surprised they ticketed it. The OP didn't say what terminal they're leaving from, but BA quotes the minimum connection time between T3 and T1 or T2 as 75 minutes, T4 as 90 minutes:
