In short, yes you will have to wait for the airport as OLCI then does not work either. At least in my experience.
No, the US site won't work in some cases because the JL flight won't show up even if you enter your JL PNR. It is the marketing carrier that's responsible for selecting a seat so OP needs to call AA or wait till AA OLCI opens which is T-24 instead of T-72.
