I think Terran history would be very likely to be fascinating to the 3I because of its drama. Much of Villani history is dull and or repetitive. They lived in a socially engineered society meant to be static and unchanging. That makes for dull history.

Terra's history has a dramatic quality because of its changes and growth. People will seek this stuf out in the same way they seek out exciting fiction.

Besides, Traveler has nearly always been "Brits in Space!!!!!!" It's the British Empire and a mixture of Victorian and Stuart tropes and stereotypes. The "Yanks in Space" line was always meaningless. The British Empire is clearly important in the 3I.
