I was able to determine that this is actually a bug in Arduino CLI, so I have transferred the issue to the appropriate repository.
This is not in any way specific to the Teensy Arduino boards platform, but that platform does provide a dramatic demonstration of the bug due to the Library Manager installation of "SD" being given priority over the platform bundled installation. In most cases (e.g., "USBHost" lib and arduino:samd platform), the bundled library gets priority, so the bug only manifests in the oddity of the library removed from <directories.user>/libraries still appearing under a "Multiple libraries were found for" section of the verbose compilation output.
I bisected the bug to f0245bc2da6a56fccea7b2c9ea09e85fdcc52cb8
In case it might assist the developers in the investigation, I'll provide a demo of the issue using Arduino CLI directly:

0🐛 The second compilation failed. It was necessary to reinitialize Arduino CLI in order to get it to recognize the removal of the library.

Describe the problem
I installed RC7 on new machine (RPI4 running Ubuntu 22.04). But pretty sure other setups would work the same.
I then installed the Teensy boards, which installs it's own SD library (~/.arduino15/packages/teensy/hardware...)
I then opened a sketch and tried to compile it, I received several strange errors and then remembered it was using the old SD library. So opened up Arduino/libraries folder and deleted SD.
I then tried to build again.
The compiler then failed with error saying that it used: SD.h from the Arduino/libraries/SD folder and not the one from the teensy install. And then gave error that the file did not exist.
To reproduce
Described above.
Expected behavior
Would expect it to see that the folder did not exist and then do the find of it again.
Note: I also tried closing the window and reopen it and it still gave same error.
Arduino IDE version
RC7
Operating system
Linux
Operating system version
Ubuntu 22.04 (RPI 64 bit)
Additional context
Sort of related to my arduino/arduino-ide#798, where I would hope if I had a custom version already installed it would not overwrite.
Also tried to search for duplicate but hard to find search terms.
