But he is not the lead.
One could argue that Ashe is the lead, or that balthier is, or basche... it's all up to your interpretation. All of the characters in this game have deep well-developed arcs that are well written and well done. Vaan may be purely along for the ride, but he matures greatly as the story goes on and he turns into quite the likable character. The only character who kind of feels out of place is penelo, but she's there to watch after vaan so it still makes sense.
