I was looking at route-views.routeviews.org for the BGP routes and i
dont see any AS-Sets whatsoever. Are BGP routes with AS-SETs not
generally leaked into the wild?

Is this the case?
I guess they aren't.

I am under the impression that AS_SETs are generated whenever there
are some routes that are aggregated.
Yes, but aggregation in the BGP protocol is a relic from the BGP3-to- BGP4 transition, AFAIK it's rarely used these days.
