It depends actually. While Riven does nice damage at the start of the game, she's still a bit fragile if zoned. The extra AD marks give her 3 things in early game: 1. Laning presence, 2. Better farm, and 3. Better survivability. Armor Pen is by far more useful when scaled throughout the whole game, but AD is just to give her an early game edge. New/Inexperienced Riven players should go with AD runes, but Veteran Rivens should definitely use Armor Pen.
