“Have you taken a look at the amount of fat, i.e. oil, that is in these “healthy” chips?”
Yes, I absolutely have looked and they are relatively “healthier” than regular potato chips. For a typical 1 oz serving (which seems to be the standard metric even though most of us grab more) the Terra Chips have roughly half the saturated a total fat of regular kettle potato chips and also have lower sugar and sodium percentages depending on which brand of potato chips you are comparing.
The BEST (aka healthiest) alternative would be making your own veggie chips at hope in an air fryer. I’ve tried making them a few times and they are OK but not as good as the Terra Chips.
