Quick noob question
When an ability has damage reduction, does it reduce true dmg? (I. E. Garen's W, Kat's E etc)

no
It doesn't.
I don't believe Garen's W does, at least not according to the LoL wiki, Katarina's E and Alistar's R don't state one way or the other so maybe?
That's actually a pretty good question.
No, true damage is not blocked or reduced by anything
true damage cannot be reduced by any means. If it could be mitigated then it wouldn't be "true" damage.
