bicycle laws in the US are by state/city/county and rarely national. there is no single traffic/bicycle laws -- they vary.
I think the reason for it is based in the belief that the right hand is dominant for most people and that a quick brake with the dominant would result in an endo over the bars. Of course, this is generally nonsense.
cyclists in the uk typically do right-lever-front brake, but the rest of europe does left-lever-front brake.
just do what you like. I prefer left-lever-front brake because that's what I have always used.
