He was not meant to be a support, but that does not mean she isn't a support. None of the champions you mention have "support utilty", and by that I mean heals/sustain, shields, etc...

Does Sejuani have a shield for allies? Does Ekko have heals for allies? Doubt it. The reasons why they are not regarded as a support is that they are more beneficial in their respective areas: Sejuani excels in ganking and tanking damage more (with her Q gapcloser and her R), while Ekko excels in catching enemies off-guard and dealing burst damage. Having Ekko as a support is not the worst thing that can happen, but it's not definite not a good idea because Ekko's AP ratios are top notch and being a support isn't favorable in acquiring AP.

Shen on the other hand, has everything a support needs. You want heals for allies? His Q gives him that. You want global shields for allies with global teleport that can turn tides of teamfights? Shen offers that. You want hard cc? Shen offers that too. Sure he might not be supposed to be a support, but he has all it needs to be a support.
