Won’t work sadly, the “counter sound” can’t be in phase in multiple locations because of delay and reflections. Headphones can do ANC because the ear is basically a single point so the mic can pick up exactly what you’re about to hear and then compensate.
Using a speaker like that would just create double the leafblower noise.
Using the same principle as noise cancelling headphones, you could just blast an equally loud counter sound to negate the blower’s noise.
But where’s the fun in that?

I mean, would they even hear anything over the leafblower?
Or leafblowers could include that as a mandatory feature
Okay! I’ll make sure to blast my sirens at my neighbour next time he leafblows. That totally won’t get me in any trouble whatsoever lmao
