Why does Ornn have the same attack range as Yasuo

Ornn's arm is easily longer than Yasuo's arm, so it evens out.

If I remember correctly, standard is 125, with a few at 150, and Yasuo, and now Ornn being the special kids at 175

I think longer range is intended for most champs, but a lot of the older ones have model/animation limitations that prevent them from having that range. Yasuo and Ornn were designed to have longer range from the start.

IIRC they did a pass back during the juggernaut update that gave a lot of melee champions 175 or at least 175 with aa enhancers like garen q.
