Surely it is well known that the Ope Ope no mi can cure almost any disease.
What’s more, Law was even a well known pirate at the time. Ace even mentioned his name to Yamato, an event I believe happened near the time Kuma was looking for doctors to cure Bonney.
I feel like at the very least, Oda should have shown Kuma asking Law for help with Law stating that even his powers can’t cure Bonney.
Otherwise this scenario honestly seems a bit contrived.
