The creators of the anime wouldn't know his age. They just pick the voice actor with the voice they like.

Since he doesn't have any wrinkles, he could be in his teens up to his thirties. It's hard to judge age clearly with anime and manga characters. Only Kagami would know the truth... I don't believe Lacus has appeared in any of the light novels.
