If B decides to use his 7 swords dance, Hiashi can simply rotate or use Vacuum palm. Bee would not Blitz someone who has better reflexes than Itachi and Kisame.
where did you get Hiashi having better reflexes than kisame and itachi?
V2 is the problem but I believe Hiashi can react to him if it comes down to Taijutsu. Not to mention the range of his rotation. He doesn't need to fully rotate. The slightest would send Bee flying

and it would knock away B's chakra

It will only knock away bee's chakra if it's powerful enough to do so. Bee's V1 lariat is powerful enough to do

. I think hiashi's kaiten could be powerful enough to deflect that,

However, a V2 lariat is on a totally different level of power than that considering the mode was stated to be 'incomparably more chakra' than V1, and kisame took more damage from the V2 lariat than Sasuke did despite blocking the attack first with samehada.
V2 lariat would go through hiashi's rotation and kill him. the V1 lariat would probably explode, resulting in hiashi and bee taking an explosion like naruto and neji did. However Bee is far more durable than hiashi and therefore would win.
If B decides to transform and use Eight tails whirlwind, while his wrapping himself with his tails, Hiashi can use Vacuum wall palm that was shown to be able to deflect his the ten tails hand which was shown to be comparable to or even bigger than the 8tails in size

The juubi's tails being bigger than bee's tails doesn't mean that a single tail of the juubi > 8 tailed whirlwind. The tail taht hiashi deflected had such little power behind it that it didn't even generate a shockwave. Compare that to the V1 juubi doing

with a single tail swipe and you can easily see the juubi wasn't swinging its tail with any significant force.
That said though, the whirlwind is massive in AoE, but that doesn't necessarily mean it's all that powerful against a single target. It's not an explosion, it's more like tenpenchii where it does a lot of damage spread around, so I can see hiashi withstanding it with a massive kaiten.
At the end of the day though, Hiashi loses pretty badly. He's not more reflexive than 3 tomoe sasuke so he'd probably have to bail himself out against the 7 sword dance a lot with his kaiten. At worst, bee would have to use V1 to secure the win. And being a jinchuriki, the hyuuga's chakra point pressing is practically useless as the activation of a bijuu cloak is enough force to open them back up. Bee doesn't even need his
