What did aggressive players like Tal, Fischer, and Kasparov play as white?
The Ruy Lopez.
Looking for an aggressive non-gambit white opening
Colle-Zukertort attack aka Colle: Rubinstein Variation
Looks very passive ngl.
I beat Wally with it in 23 moves with it. While it looks passive in the beginning, I have found the middle game to be very quick in most games since it's a very trade happy set up. That set up also is against passive players. With more aggressive players playing black, both sides get to an end game fairly quickly.

You're not playing it right then, the entire premise of the opening is to launch a huge kingside attack with f4 + g4 to land some sort of Qh5 mate threats, if you trade all your pieces off then that won't be possible
Thank you, this has really helped me for now.
