In theory it is still possible for BA to re-route me. Instead of going direct from LHR to LAS, there are connections available via ORD and LAX.
Will BA just cancel my flight or will they initially put me on a connecting flight?
Probably they will just cancel and not automatically offer you an alternative via another entry point in the US - it doesn't limit your options either way though.
Finally, will it be possible for me to change to a connecting flight of my choice?
I don't really want to do this trip now. But if I must, I would be better off going TATL on AA rather than BA.
Yes you can. However, you get one shot at the involuntary change so once you have done your change any further changes/cancellations will be according to the fare rules.
