Even if there were, it wouldn't be very useful. In a "common law" system like the US, legal questions are rarely answered purely by the plain text of a law. You also need case law - that is, how the law is typically applied in practice by the courts.
Sure, then that with case law too?
The legislation seems more high-level requirements, that then implemented over in the Code of Federal Regs[1].
Using AI to plow through and make sense of all this would put us at risk of people knowing what the USG is getting up to.
