Personally, I think the difference in style makes it fairly easy to figure out who wrote which songs/sections, though there are some that could go either way.
Luckily, there is a copy of the full score (of questional legality) which is floating around, and it lists who wrote each song. If - hypothetically - I were morally debase enough to set eyes upon an illegal copy of a Broadway score, then in that hypothetical scenario, I might tell you that this is the breakdown:
"What I Was Born to Do"
Music by LMM and TK
Lyrics by LMM
Additional lyrics by Amanda Green
"Happy Kitties"
Music: TK
Lyrics: AG
"Tryouts"
Music: TK
Lyrics: AG
"One Perfect Moment"
Music & Lyrics by TK, LMM, & AG
(I suspect most of this song was written by TK, with LMM writing the intro - that's just my guess though. That's the way it sounds stylistically, plus the reprise of "One Perfect Moment" only lists TK, and it doesn't feature the intro section).
