In New England, I've never seen anything other than a magstripe insert-remove type reader in a gas pump (although I think some do contactless EMV).
FWIW, At least in MA, it's rare to see a gas pump older than 10 years -- I think due to both Federal and MA State UST laws that require fairly recent (e.g. 2019) minimum standards such as double walled, properly cathodized, leak detecting tanks along with subsidies for tank replacement that have resulted in pretty much every gas station around here being totally renovated in the past 5 years or so.
Never been to a pump that uses chip personally, unless you pay inside. I've seen ~5 with a contactless tap point, but only got about 2 of them to work.
