My iphone keeps failing to update. I'm trying to update through a mac but iTunes has been replaced on Bigsur. Any ideas how to do it?

Use the Finder to sync your iPhone, iPad, or iPod with your Mac...

Everything you did in iTunes (related to managing your iOS devices) is in the Finder. When you connect your iPhone, it should show up in the Sidebar in a Finder window.
