BA will be aware that (currently) if they carry you to the USA, they will be obliged to fly you straight back to the UK when you're not allowed in.
If their reservations people are pretending otherwise, they are either stupid or disingenuous. Should you show up at LHR with your ticket, you will be denied boarding - but it shouldn't be necessary to go to those lengths in order to secure a refund.
You are unlikely to be alone in this situation - there must be thousands of passengers currently holding UK-US tickets who are unable to fly.
