Americanized Chinese food would probably make up most of what Americans are eating as Chinese food, so the Taco Bell comparison is apt.

American Chinese food is a lot sweeter, thicker, and more soy sauce based.

It’s still not an appropriate comparison. Taco Bell is junk food. Americanized Chinese food (or Mexican food) is not at the same level unless you’re intentionally using that term as a pejorative.

Your equivalent statement about Mexican food would be that you assume Taco Bell is what most Americans are eating as Mexican food. That doesn’t seem a valid assumption at all - maybe for a certain demographic (e.g. young) that’s true, but I’m very skeptical that such a claim would stand up to scrutiny.

Similarly, you cannot group the corner store (nominally) Chinese restaurant owned by a Chinese (or as likely in much of US, Korean) family as being in the class of highly processed, pre-made food as Taco Bell. Sorry but no.
