It isn't about the lifesteal, it's about the raw AD. The lifesteal helps regardless because they do auto attack, but it isn't the main stat you're going after on an AD caster.

On auto attackers like the ones you listed it's better they go for a combination of stats, not just stacking lifesteal and AD. They would do better going for items like Phantom Dancer, for attack speed, movement speed, and critical strike chance and Infinity Edge for the attack damage, critical strike chance, and the improvement to critical strike damage.
