Well it seems i was incorrect from the get go. The version 4 repo has a footprint with that name in it: Inductors_THT.pretty/L_Toroid_Vertical_L16.5mm_W11.4mm_P7.62mm_Pulse_KM-2.kicad_mod at master · KiCad/Inductors_THT.pretty · GitHub
Seems like we had the Pitch prefix already shortened in that particular repo (so the old footprint repos were worse than i remembered).
Which means the user just needs to add that library to their setup via the library wizard (directly from gitlab or follow the local installation guide in How can i install a specific version of the footprint library?). So new assumption: this is a group project and there are differences in library setup as the different students are on different platforms or one student did some steps that @Giovanni did not follow (v4 is too long back so i can not remember if i needed to do something to get all footprint libs. I just know that by default only a small fraction of symbol libs was available.)
