Too late to help the OP, I'm sure, but because this question was never answered, I will answer it. Yes, an AA codeshare pax who has his/her WestJet booking reference can do OLCI and select seats 24 hours before departure.
The WestJet booking reference is not the same as the AA locator, but any AA phone agent can provide it.
