I don't care for it right now, but might some other time.
Ottilie is much, much more agreeable, and what pretty name it is.
Ottoline just seems like a name-nerd nerdy name to me: some weird Edwardian antique invention that never took off because it didn't make life any better, like the electric table cloth (it's a real thing!).
You could maybe get away with
Lottie or
Ollie.
