SdFat is GPLv3.
The SdFat part of the SD library is GPLv3 also. Read the comments . It is clearly GPLv3.

Subject: [greiman/SdFat] License of SDFat? (#46)
Hi,
I might be blind, and while I can see that SDFat is GPL as per the comments in the code, which version of GPL is it under? According to the Arduino folks, all of the core libraries are LGPL, and SD (based on this I believe) is part of the core library. Does that mean that SDFat is LGPL?
Thanks,
Jeremy

Ok, thank you! I was confused because the arduino FAQ says that the core libraries are LGPL: https://www.arduino.cc/en/Main/FAQ
And SD is considered to be a core library here: https://www.arduino.cc/en/Reference/Libraries
from sdfat.
SD is not a core library. It is a "Standard Library". Look at the various "Standard Libraries", few are LGPL.
Look at SD.h it is licensed GPLv3:
/*
SD - a slightly more friendly wrapper for sdfatlib
This library aims to expose a subset of SD card functionality
in the form of a higher level "wrapper" object.
License: GNU General Public License V3
(Because sdfatlib is licensed with this.)
