And to prove it, I will recount the in game background for both race/class combinations.
Zandalari paladins are based off trash mobs in a raid, and quest text from Zul'gurub armor quests. There, the Zandalari say, that the beliefs of the paladins are foreign to them, and that they are heathens within Zandalari society. This arguably lends as much credence to them not being "proper paladins" or at least a minor faction in Zandalar.
In BfA they are giving us the background for the Prelates we encounter in Throne of Thunder, but (spoiler alert) they lose their god and source of power during the story.
In WC2, Kul Tiras used mage units, and in WC3 they had archmages and hydromancers. Of course, this was perhaps to fit in with the tech trees of other Alliance factions, but consider that the Hydromancer was added specifically as a human replacement to the elven sorceresses.
Baradin Hold was built by Kul Tiran wizards according to Cataclysm lore, that does not seem refuted so far.
Probably. I cannot find any mention that Jaina was estranged because of arcane magic or that Kul Tirans hold a general distrust of it. Current lore is that Katherine managed to get the Kirin Tor to tutor her prodigal daughter, and nothing older I can find seem to indicate otherwise. If anything, she was the "pride of her nations eye" prior to Daelin's death.
All the other human kingdoms have historically had mages, but there is a great lack of explicit mages on Kul Tiras in BfA. Its portal and enchanting trainers are tidesages, who seem to hold the general place of utility casters within Kul Tiran society.
I will admit I get into speculations, but several places in Stormsong Valley I recall arcane-like particles from the spells the tidesages cast (only the bridge to Shrine of Storms come to mind right now). If the tidesages practices are more natural than divine in origin, then maybe arcane and worship is blending more in Kul Tiran society than the other kingdoms, who worship the Light.
We know that darker factions in Kul Tiras probably use arcane magic, as the fire casters are either arcane in style of fire mages and destruction warlocks, or divine like a shaman or tidesage, and so far we don't know of a fire counterpart to the Tidemother.
Comparing Zandalari paladins and Kul Tiran mages is a perfectly good comparison, because it compares two very similar things, like what background would that class have. Arguably, Blizzard has implemented better and worse fits already, so there is not one single standard and really anything goes. And I guess that is what you mean.
