The end with the "dot" does make a difference. ?If you rotated or mirrored an inductor on the LTspice schematic so that the "dot" swapped locations with respect to the rest of the circuit, that would be the same as either (a) swapping the leads on that particular winding, or (b) winding it in the opposite direction (counter-clockwise rather than clockwise).

Of course, rotating an inductor while leaving its ends connected the same as before, changes nothing. ?Hopefully you knew that already.

The convention of using "dots" on transformer windings has been around for decades. ?You should find information about it going back a very long time ... probably to before any of us was born.
