You don't. XFS doesn't support shrinking.
For this much of a size difference, do a reinstall.

In theory you could copy everything off 'rhel-root' to another system (or external disk), shrink the LV, recreate the XFS filesystem, then copy everything back. If it doesn't work however, you'll need to re-install the system.
For the time it takes to successfully plan and execute that, it's probably quicker to re-install the system

I've attempted to grow (you are interested in shrinking) a root "/" volume on a RHEL 7 system, and even though I did lots of research, and lots of preparation, it went very poorly, and I ended up reloading the system. There's enough risk with attempting atypical resizing of the root "/" partition that the pain of that will out-weigh reloading or kickstarting the system.
I agree with Marcus & Jamie above, yes, it's painful to reload, but it's the best viable option. You could create a kickstart from the /root/anaconda-ks.cfg and adjust the partitions accordingly to make it a little easier. You could stage the kickstart on another Linux system on a web server that can be "seen" on the network by the system you're kickstarting.
Kind Regards, -RJ
