I wrote up such a character for Xendrik Expeditions.
Halfling Ranger (Archery track, ACF to swap out Animal Companion for Distracting Attack from PHB2), with the Grenadier Feat (PHB2) and Shaped Splash feat (Races of Eberron). He had Craft (alchemy) and threw Alchemist's Fire, Acid, etc.
The RPGA has special rules for 'expendable' or 'consumable' items. Spend 5x the base price, but they are assumed to 'come back' at the end of an adventure / session, so he was designed to cruelly exploit that rule, flinging alchemist's fire with abandon, since it would all just 'come back' for the next game. But yeah, given the cost of his missiles, his entire focus was basically 'throwing money at people.'
