I agree that your AP Computer Science class is in no way equivalent of a four-year college degree in computer science, and just because you were bored in a high school AP class doesn’t mean you’re ready to start graduate work in computer science. (For one, CS degrees are about way more than programming.) AP CS represents just one single very intro level class in a college CS curriculum.
Reputable graduate programs require an undergraduate degree. They’re called graduate degrees for a reason - they rely on a foundation of knowledge that you build in undergrad. They don’t really make exceptions for that. If a program was going to make a rare exception, it probably wouldn’t be for a high school senior who has taken one AP class and a bunch of online MOOCs (which most graduate degrees don’t give formal credit for yet, btw).
If you call a computer science department, the person who answers the phone is usually the departmental secretary. Departmental secretaries know everything - especially the ones who have been around for long time - because everything that happens in the department usually passes through their office at some point. If anyone has ever gotten in without an undergrad degree, they would know; so if they’re repeating the rules to you it’s because they’re trying to politely tell you that you’ve got to follow them.
If you called the admissions office…same thing. They’d know if a high school student was admitted straight to a master’s program without a college degree.
Concentrate on finding colleges with computer science degrees. If you’re this great, you should have no problem gaining admission to a CS BA program and finishing it up.
(Also, quantity of the “letters behind your name” doesn’t matter; the content and quality of the letters matters. This is especially true if the two additional certificates are essentially the same thing just with a different name or institution.)
