"Vorpal Spikes procs spell vamp and Rylai's slow similarly with all area of effect spells and abilities with diminished effect. "

Why wouldn't it anyways? It's not like it's an On-Hit effect.

"Vorpal Spikes is a toggled conic area of effect ability that, when active, sends out a wave of spikes in front of Cho'Gath whenever he lands an autoattack. This wave travels outward in a cone, dealing magic damage to enemy units hit."

And yes Lindry's should work too.
