The underlying cause for the ore to spawn in the overworld is that it's not actually limited to the nether (I don't think minecraft even supports this without some hackery), but rather to nether blocks. So this part is OK.
The visible iesnium ore spawning reminds me of another 1.18 issue ( #584 ) where the wrong ore block was set up with worldgen. Could you test (using the divination rod) if proper "hidden" iesnium spawns in the nether? (ideally in a new world on your pack).
I suspect your generated world is either from before fixing that issue, or the datapack for terralith still has the jsons from before that fix.

Describe the bug iesnium can conditionally spawn in the overworld, visible to plain sight and mineable with a stone pickaxe
To Reproduce Steps to reproduce the behavior:
Expected behavior i'm pretty sure i'm not supposed to find iesnium out in the overworld, and i'm pretty sure i'm not supposed to be able to mine it with a basic stone pickaxe

i also wouldn't be surprised if anything that uses similar nether blocks in the overworld as part of world generation could produce this result.
note that terralith is 100% datapack based, and thus not using forge hooks. this is effectively vanilla worldgen, which might potentially be part of the issue.
