Indeed, Paraguay does not have a proper national airline since the death of LAP-Lineas Aereas Paraguayas (Air Paraguay).
Now TAM Mercosur (PZ) takes the place of the carrier of Paraguay, connecting the country with the rest of South America and with Brazil, where JJ
takes them abroad.
If we want to open the chances to "what country don't have a flag carrier flying international, Ecuador and Peru can be added to the list (although I'm not sure, I think TAME Ecuador does fly to Venezuela or Colombia).
