For context, the "almost no crops" that are irrigated comprises about fifty-five million acres, a little over 7% of cropland & pastures. Removing pastures from this data is difficult, but since we're only looking at three hundred million acres primary cropland in the US, we can confidently approximate between a tenth and a sixth of primary crops are irrigated.

I believe around 50% of that 55M acres are hay/forage/pasture. Nebraska and Colorado are easily top players. I underestimated the delta. Point remains there isn’t a ton a irrigated production for commodity crops (corn/soy/wheat/cotton)

Do you know if things like sprinklers count as irrigation? I grew up spending a lot of time in Delaware which is tons of farmland, and I remember seeing lots of weird watering devices and sprinklers.

Yes, they absolutely do.
