I honestly don't know what the 'ok symbol' is in relation to racism/whatever. In my country I don't think it is a thing and I stopped following silly things on the internet. BUT even if it is a racist symbol/white supremacy/whatever, your wife is still in the wrong. (I am assuming the symbol is not illegal)

Your wife punished a kid for making a symbol she disagrees with, heck, you could even say by making a political statement. If that happened to my kid I would probably go after you as well (not in social media, but with a formal complain to the school to get you punished).

If he wore a MAGA hat would she made him run laps? What about a BLM tshirt? Rainbow pin?

It is not her job to punish someone she disagrees with. She can talk with him and explain what the symbol means and let the kid make his own conclusion, but she can't, and shouldn't punish a kid for disagreeing with him. (which I think is the reason we are now in this place in the world, where you either agree with everything I defend or you are a racist/fascist, or if you are from the other side, you are a communist hippie skyflower)

In the US, showing the ok symbol, usually upside down, is a kid's game. If an American child shows that to you below their waist, and you witness it, then they have 'earned' the right to punch your shoulder. That kid probably punched his whole class.

FWIW, that is also a common children's game here in Austria (and many other countries in Europe, I believe).
