Crimp connections are legal splices if used in the proper enclosure.

I recently replaced our old fluorescent undercabinet lamps with new LED
fixtures. Unfortunately, I could not find a junction box thin enough to
mount under my cabinet. The romex cable already came out of the wall, so I
used crimp connectors and heat shrink tubing to connect the transformer
cord to the romex. I'm sure it doesn't meet code, but it's secure and
easily accessable from under the cabinet.

If he ran this cord to a surface mounted box and used a suitable entry
connector I doubt any inspector would have a problem with it but if
this cord goes into a wall, it is clearly a violation.

Could he install the outlet above the cabinet, then run the lamp cord
through the cabinet to plug in the outlet above (with some kind of physical
protection for the cord)?

I used that method when we remodeled my in-laws house, but I had built
dedicated chases in the cabinets for the cord to pass through. Once the
cabinets were installed, I simply slipped the lamp cord up through the
chase and plugged them into the outlets above. The outlets aren't visible
from below unless you stand on a ladder.

They have some cord protecting stuff that just sticks to surfaces. It
is a plastic "C" shaped stuff that the cord snaps into then you peel
and stick. Legal and not bad looking.
