Even in this case, someone on a flight EZE-LAX might've paid more for the same class, same time, same flight than someone on the same flight booked SCL-EZE-LAX or LAX-EZE-LAX (as in your example)

Whereas an apple is an apple in any market, a ticket EZE-LAX is not the same product as a ticket LAX-EZE. That it's cheaper in an "external" market is really an accident--it could just as easily be the other way around (also price discrimination, but not "dumping"?) or involve a third country
Anti-dumping laws are country-specific, so I don't know which ones would apply here. There's no general international law (even customary) against dumping
