you also have to remember that tobirama is a senju and as such we do not know exactly how much chakra he has. we know that hashirama has chakra that surpasses a bijuu

and even than his chakra doesn't have to be of a huge volume as senju chakra is simply really powerful because it originated from hagoromo we do know that he has skill in all elements which is a testament to how powerful he is generally only shinobi with massive chakra levels have all the basic chakra natures

knowing tobirama he likely developed many techniques that can slow down someone like Ay who knows he may very well might have some wind release sealing jutsu that can nullify a lightning armor

on a side note Ay is not an actual name Ay is a designation as in Tag team member Ay and tag team member B ie Fourth Raikage Ay and Killer B
