Orochimaru is both stronger and hardcounters Kisame, his fighting style revolves on snakes summons/forms which are not chakra-constructs, this way Kisame's main point (chakra absorption) becomes completly irrelevant.
Orochimaru can wins thanks Kusanagi that tore sent KN4 Naruto flying through a forest and had him pinned down.
Only reason he survived was because of his cloak. Any other character w/o some sort of special defense would have been peirced and torn apart from getting slammed through hundreds of trees. Samehada will not help here.
There's also Hydra which is bigger than Manda and has regenerative powers comparable to Orochimaru.
And there is White Snake poison. It also hardcounter Kisame regenerative power (coming from Samehada).
Daikodan can walled and redirected by Rashomon gates.
And against Kisamehada big water dome. Manda can lifts him out the dome. Snakes are also aquatic. You probably gonna say:
"How is Manda going to lift him out of the dome? It travels with Kisame; he'll just swim around the two until they die or drown. Kisamehada in the dome is faster than v2 Killer Bee and he is sensor"
Orochimaru can perhaps also use other snakes summon (perhaps Manda himself) to busy Kisamehada while himself (in an other snake) go out of the dome.... Orin fact just using Manda to going underground lol (if in fact Manda isn't aquatic. Even if Manda II was).
As for the rest, it's not the "basic" Suiton and Sharks that will overcome a puncture-proof like Orochimaru.
Orochimaru mid-high diff.

Also, as for countering the water dome, your point only makes sense if you consider Kisame to be stupid. He's experienced in combat. He never let a single target escape in his entire career. Why would Orochimaru be any different when he had dealt with similar level/superior opponents like Bee with no issue?
Hydra is smaller than Manda. Hydra was also a result of Sasuke's curse mark, which would never apply to this instance as Sasuke isn't present.
