Is Yorick Live?

not yet, no. He should be in 6.18 presumably. he's on the pbe right now
No. He just hit the PBE. Should be live by 6.19 though as it's doubtful that they'll include him in 6.18 being the patch Worlds will be played on.
More likely like Taric, on the patch of the tournament but disabled within the tournament itself.
