Why on earth would you want to prosecute the supermarket where ICE buys loo roll? The builders merchant who sold them fence posts?

I mean, the hyperbole is real here - because there's zero chance the international courts prosecute any US citizen - but if they did it's not going to be the people who sold them spreadsheet software.

Perhaps for the same reason the US extended its trade embargo with Cuba to include foreign companies trading with Cuba - https://en.wikipedia.org/wiki/Helms%E2%80%93Burton_Act

Or for the reasons that people have divested from companies doing business with South Africa under apartheid, or the Boycott, Divestment and Sanctions Movement regarding Israel, or any of a number of other examples.

In mafiya/organized crime, (serial) murder cases it's common to prosecute knowing supporters as "aiding in criminal activities". The supermarket cashier selling loo rolls to the ICE may not be a "knowing supporter", but the fence post seller certainly is.

As for the people involved: there won't be justice, not as long as the US has nukes and refuses any international control.

This is an utterly ridiculous statement. ICE buys their envelopes from Office Depot (example), they buy cell phones from ATT (example) - is Office Depot supposed to physically stop ICE agents from entering their stores and paying for office supplies? Is ATT supposed to refund ICE their money and immediately cancel all their phone service.

The rhetoric is really getting ahead of the reality here...

Smells like IBM supplying tabulating machines to the Nazi government...
