She's more clever than honest.
Literal
She [topic-は] honest [rather than-というより] clever is.
~というより means 'rather than' or 'more X than Y' — it corrects or refines a description. The structure says: calling her honest isn't quite right; 'clever' fits better. 利口 (りこう) means 'clever' or 'shrewd,' carrying a slightly calculating nuance compared to the purely positive 賢い (wise/smart).
