Consider how many American companies exclusively manufacture in the far east.

If a European buys a product "made by" Apple or nvidia or Nike or Levis - that's not an American export, it's an export of Indonesia, China, Vietnam, Taiwan, or wherever. America still gets the profits, though.

Airliners and military aircraft are expensive. Consider that nearly the entire aircraft production capacity of Boeing and Lockheed-Martin as well as the engine production capacity of GE and P&W are booked for years to come. Also, unlike Airbus which has multiple final assembly plants across the world, Boeing only does final assembly in the US.

As for aircraft, not that many in number, but very expensive things with very expensive parts.

A lot of components are actually imports from other countries, eg Japan manufactures wings.

We don't export nor import "net" anything. The definition of exports is not affected by imports.

So many trillion-dollar valued AI-focused companies.

How are service exports counted? All together? Or not considered exports?

It’s conventional, in American English, for exports unadorned to mean just goods. It’s anachronistic. But it isn’t wrong.
