is ad alistar still viable after patch 4.14?

Depends.

Jungle Alistar/Jungle Support Alistar? Or is his lane opponent super passive as well?

it works, but it's not really optimal. you can win games with it because people are bad and they might feed you but it doesn't scale at all. you're essentially wasting his passive damage and you're going to get kited 100% of the time that your W+Q combo isn't up.
