Not gonna happen.
Data brokers like LexisNexis ingest and correlate a ton of information about individuals. Access to this information is theoretically tightly controlled, and restricted to organizations like law enforcement, skip tracers, PIs, debt collectors, and so on. Joe Consumer can't just go sign up for an account and start digging. That's just one commercial data broker. In addition, law enforcement agencies typically have their own databases that they rely on. There are low rent alternatives like FastPeopleSearch and Intelius that give you far less information with varying degrees of accuracy, but that's a little like comparing a 95 Honda Civic hatchback with a faded "TYPE R" sticker to, I dunno, an F15.
However, if you ever get the opportunity, seeing your own report is fascinating. For a typical adult expect 50+ pages of information. It's not just raw data, but carefully correlated information to paint a picture of who (and what) you are. I haven't used LexisNexis in years but you may be able to hire a PI to pull your data.
EDIT: Oh here you go. You can order "your report" from them. I'm not sure if this is the full book-size report or not, but it's worth a shot.
I’m curious but also paranoid on what am I giving them by requesting this info lol the vicious cycle continues.
I assure you, you can't tell LexisNexis anything LexisNexis doesn't already know about you.
On the other hand, they can probably tell you a few new things about yourself.
