The answer is just laws and taxes. Most European and Asian countries have displacement taxes, power taxes, and much higher fuel prices than the US. For these reasons manufacturers design their cars around these markets. For example Japan has significant taxes and fees for cars above a certain physical size so the Kei car concept exists there. The US has no such laws so there is no reason to make those cars here. Many countries tax displacement typically the lowest cutoff is around 2 liters so you see engines like the 1.5 liter MX5 popular in those regions whereas in the US it is a 2.0 liter. The Fiat Multiair 1.3 liter is another example of an engine which was designed to be economical under those tax laws.
If you actually look into it the LS V8 engine is similar size and weight to the turbo six Euro engines it often competes against, and in fact usually gets comparable mileage (actually much better highway mileage in some cases). But due to taxes in Europe it costs a fortune to own a V8, so they are reserved for very high price cars only. The concept of a "cheap V8 car" simply can not exist there, so they ONLY end up in high end cars where the buyer is so rich they simply don't care.
Here's an article about one specific example, where Ferrari designed a new engine/car specifically to avoid high luxury taxes in Italy. https://rossoautomobili.com/blogs/magazine/taxes-made-the-ferrari-208-the-slowest-prancing-horse
Sometimes you can find examples where manufacturers swap engines to dodge taxes in a new market. I find this stuff interesting because it contributes to the car culture in each country. Enthusiasts do their best to have fun while working within the laws so you end up with neat and creative car designs.
