The US was quite isolationist up until the end of WW2, so I’d argue global hegemony isn’t that important when it comes to economic performance.
Spanish American war was mostly isolated to the Western hemisphere (although the US gained colonial possessions after).
It took forever to join WW1 due to the small size of the US standing military. Same with WW2.
It wasn’t until after WW2 the US was able to project power globally and through that, set the global power structure with the USSR.
"The US was quite isolationist up until the end of WW2"
Being involved in these wars, regardless of entry time, is on no way "quite isolationist'
The US growth trend has been fairly constant since the late 1800s. There's no real discontinuity in the trend around the time the US become hegemon.
