I use OmniGraffle for creating figures for use in LaTeX documents all 
the time.  OG will export a selection to pdf or eps format (among many 
other formats).

I haven't played with it for making Venn diagrams, but it seems like 
one could draw circle with a gray-scale, partially transparent fill.  
Overlapping these circles would then result in a darker shade for the 
intersection.

Cheers,
