ENTJs have Dominant Te and Tertiary Fi. ENFPs have Auxiliary Fi and Tertiary Te. Why would it be hard to confuse the two types? Particularly when the differences between Ne and Ni are so hard to quantify, and the public expression of Ne is often frowned upon?
No they actually have inferior Fi.
ThatGirl does not fit the ENFP profile. Compare any other ENFP with Thatgirl and there will be a contrast.
