The OP is correct that BA will most certainly refuse to create award space on LHR-LAX, which sells extremely well in F in the first place, where it can instead offer a later LHR-SEA.
BA may also be amenable to letting you fly on another day (on the same route) if it is of interest as the SEA flight only goes at 8.50 one day a week.
Unfortunately, both airlines tend to be rather narrow minded when one seeks to resolve a timetable change through a rerouting on a different origin or destination, but if you want to go that way, I would suggest pushing the AA flight option as it is (in my view) slightly less unlikely that they will say yes compared to BA.
Depending how the agent reads BA's re-booking guidelines it still may be possible. Re-booking into the lowest available booking class applies to both commercial and redemption bookings. So, that's taken care of, and no award space needs to be created, as I mentioned before. And then there is this langauge:
If the passenger declines the options to rebook or refund, then they may be offered the option to reroute to an alternative gateway following the guidelines below.
Rebook onto the next available flight on BA, (if JB routing also use BA*AA/AA, BA*US/US, BA*AY/AY, BA*EC or BA*JL/JL), to the nearest alternative gateway within a max 300 miles radius.
I know that the last segment is operated by AS and I am not sure whether the final destination counts or SEA but it is worth calling back and enquiring. I have come across quite a few agents who are not familiar with the re-booking rules and insist that award travel can only be re-booked using redemption seats which is not correct, at least not with BA.
