APD is structured so that it is payable by the operator of the aircraft, i.e. airline, so in this case I would advise that you contact BA to confirm whether they have indeed created a connecting ticket and ask them what you need to do to secure any refund from them.
I suspect that if asked, BA would say that it has not done this. Not least is the fact that if BA created a connecting ticket, it could be contractually liable to you for misconnection protection etc.
It would be interesting if you were to get a different response from BA.
