As posted if MX was not in oneworld when the ticket was issued, then MX segments should not be able to be included now.
The actual xONEx rule regarding Cuba is:
If a ticket includes travel to/from/via Cuba it may not also include flight segments for travel on American Airlines/American Eagle including flights operated by Executive Air / American Connection including flights operated by Chautauqua due to U.S. Government restrictions. Any such ticket will not be honoured by AA and cannot be used to travel on AA.
As such the Agent is wrong about Cuba. (There is no way the ticket should have been issued in the first place had it contained any AA segments.)
