Americans usually (I think) pay sales tax, unless they are in one of the very few places that doesn't have them. A VAT is just a version of a sales tax that is harder to evade.

It’s almost impossible to do a straight comparison of taxes since the level of services is buys you from different governments is different, and each government (in American states and European countries) divvy up the taxes in varied ways between income, property, sales, tolls, and probably a whole bunch of other ones.

Sales tax exists in some states but not all. It's also less than ten percent. In my state the PS5 costs $535 after tax while in the UK it costs $587.
