"Diverse strategies" in the context of League refers to different approaches to winning the game, and not to how many roles a champion can fill. While it's sometimes fun and interesting to have a champion be viable at multiple roles, it's also extremely difficult to do right, since your champion needs to be strong in its own right without being top-tier at two different roles at the same time (this was a problem with, who could build like a fighter or an assassin and could provide top-tier supporting power alongside top-tier assassination or fighting potential). Trying to make a champion viable at multiple roles can also sometimes dilute their theme or playstyle (pre-rework top, for example), so it's not always worth the effort.

To be honest, though, Kalista has some pretty strong utility, on par with 's, and so could likely be played non-competitively as a defensive caster support. Her W contributes a ton of extra damage to the lane, plus built-in wards, her E can be used as an AoE slow, and her ultimate can be used to save her Oathsworn ally just as they're about to die.
