The LDB only canonly did the Main,Dawnguard and Dragonborn quest lines. We don't know if he joined the war and if he'd did we don't know what side he chose. The LDB can't use his blood as right to the throne because the rule for that is that you have to be related to Saint Alesia which isn't possible anymore.
