I don't think the OP has status nor will it be gained on an LONE4 with no AA segments.
However it's correct that BA is in general the worst of the lot, offering 25% miles on "L" class bookings network-wide. AA gives 100% miles on AA, RJ and LA segments, 70% on JL, 30% on IB, 25% on BA, and zilch on CX. I'd have to do the math to see how the result would stack up for the OP, but the route shown is not a valid xONEx itinerary, so once it's refined it will be easier to total up.
As for status bonuses, unfortunately you don't get AA status bonus miles for JL, nor, as of next April, BA. And as far as CX is concerned, any status bonus for L class miles will also be zilch.
