Feel free to have a go at this: https://www.congress.gov/bill/119th-congress/house-bill/6028...
It's a critical law currently working its way through congress. It's not only indecipherable, but far longer than the entire original US Constitution. And that's a trend - when things were done by people and for people, they tended to be brief and clear. As lawyers got involved, everything became a convoluted indecipherable mess which may as well be written in Latin.
That law is essentially a diff. The USC (the actual statute) tends to be easier to read through.

I took a look at a few random sections of it and didn't see anything undecipherable, other than maybe things that lack enough context because it is written as a diff from the current law.
The comparison to the length of the Constitution makes little sense to me. The Constitution establishes a framework and some power allocations. It says almost nothing about the bazillion lower level details necessary to actual have a functioning county.
