Trump has been in Argentina a number of times since 1985 - mainly as the guest of his old friend Mauricio Macri (an authoritarian idiot who bankrupted the country in 2018).
Macri owns numerous homes in the country - and would consider it an honor to house Cheeto in one of them.
And he wouldn't be the only one: Trump is widely admired by many on the Argentine right - particularly for what they see as his "fight against undesirable immigration" (by which they mean dark-skinned people).
Among his loudest such supporters, is the current president - the "Idi Amin of the Pampas," Javier Milei.
Argentina does have a mutual extradition treaty with the U.S. - but Milei (who rules mostly by decree) would be very unlikely to uphold said treaty, if Trump is convicted in a U.S. court and Milei is asked to extradite the fat bastard.
And by the time the matter is resolved (or Milei loses re-election in 2027), Cheeto, by then, will probably have kicked the bucket.
He won't be able to resist Argentine beef, you see - and what with his heart health...
