How a larger A7M Reppu force could complicate B-29 raids

Would roughly three hundred A7M Reppu fighters have disrupted B-29 firebombing and atomic-bomb missions?

They could complicate the raids, prompting different targets, diversionary attacks, or concealment of an atomic-bomb aircraft among other bombers.

A force of roughly three hundred A7M Reppu fighters could complicate B-29 firebombing and atomic-bomb missions. American planners might select targets where interception was less likely. An atomic-bomb aircraft could be concealed within a larger conventional raid, or a separate firebombing raid could divert attention while it attacked elsewhere. These alternatives would require more preparation. The contrast with the nine aircraft in the question concerns the difference between a handful of fighters and a force capable of affecting raid planning.
