Can i earn story mode trophies while playing gta online?

The only verified source provided discusses Grand Theft Auto: Vice City, a 2002 action‑adventure video game, and contains no information about trophies, achievements, or the online multiplayer component of the Grand Theft Auto series. Because the evidence does not mention GTA Online or any interaction between online play and story mode trophies, we cannot confirm that such trophies can be earned in GTA Online. Without additional reliable sources, the question remains unanswered based on the current evidence.
