It could be both. The summoning magic could be a closely guarded secret of Lyngle kingdom, leading to the rest of the world not knowing or not believing that heros a summoned beings.It seems likely that, if we go by Kiriha's surprise at learning Usato came from another world, average citizens (at least) don't believe the first hero was isekai'd, and think that's a fairytale. Plus, Usato and the others weren't summoned by an alliance, but by a single kingdom. So it might actually be possible that only Lyngle kingdom has the knowledge to summon heroes, or that no other nation knows the first hero was isekai'd.
