As for archers, do not trust only the pose of the miniatures. The Centaur hero, for example, is a good archer -- you can see the bandoleer holding its bow to his side, even if the bow itself is hidden, being on the other side of the miniature. And it seems the forest troll can hurl javelins.
That said, indeed, none of the figs are wielding a bow. Aberrations had three (elf warrior, HEBI, and yuan-ti halfblood), Giants of Legend had none too, Archfiends had four (catfolk, greycloak ranger, halfling ranger, gnoll archer), Dragoneye had only one (kapak draconian) but three if you count crossbowmen as well (human crossbowman and kobold skirmisher) and Harbinger had eight (arcane archer, centaur, elf archer, wild elf barbarian, wood elf skirmisher, medusa, drow archer, orc archer).
But that's only counting those that are sculpted as using their bow -- if you add those that are sculpted as having a bow but using another weapon (like exorcist of the silver flame or copper samurai), or those that have other sorts of ranged attacks (like goblin skirmishers with their javelins), you'll have a much higher total.
