Is there a word that means "attracted to talent" in the way that sapiosexual means attracted to intellect?

Sapiosexual is not a well-formed word but a coinage from ignorance (you might as well say brainosexual); it would have had to be sapientisexual. Anyway, it is better to use -phile. Someone ''loving'' the skilled would be dinophile. This has the same dino- as dinosaur, since δεινός means both terrible and (terribly) skilled.

If you really want a pseudo-Latinism ending in -sexual (what does sex have to do with it?) you can use dextrosexual. Unfortunately, this word is also interpretable as denoting sexual preference for one's own right hand.

There is groupie

groupie NOUN
informal
1A young woman who regularly follows a pop group or other celebrity, especially in the hope of having a sexual relationship with them.
Oxford Dictionaries

I suggest perhaps “peritiosexual” or “peritiophile”. “Perite” meaning “skilled” or “expert”.
