Any song you want to learn has a variety of rhythms.  And doing it that way has the benefit of learning rhythms in the context of music.  You'll know if you are getting it right if it sounds right!  All the GT songs have tab plus notation so you can see the fretboard location, notes & the rhythms.

But if you are referring to having the '1-e-&-a . . ." written out, then yes you'll likely have to do that yourself.  The vast majority of rhythm studies I've seen typically indicate the first measure to get you started (sort of a legend, or key), then you're supposed to just read the rhythms from the dots & beams thereafter.

Hope that helps!
