I don't believe that ANY Central or South American country lacks an extradition treaty with the US. . . . unless of course, you're thnking of Cuba, which is not really a part of the North or South American continents.
They all do.
However, since the United States has relatively weak diplomatic relations with Cuba, extradition between the two is extremely rare and a very lengthy process.
I don't believe that there are any continental South American countries that do not have an extradition agreement with the US.
