After act 2, I think you could make a case for either Fi-dom or Si-dom. Isha is obviously hard to type since they're mute, so we can't rely on explicit reasoning for their actions to see how they think. Child characters also are inherently hard to type because they might not have developed most of their functions In any case, Isha's core seems to be that they cling to their emotional connection to Jinx, and what Jinx means to them. Isha likes Jinx both as a person, but also as an idea (which is why they go ahead and act like Jinx behind her back). I wouldn't say Isha is like a Zaunite freedom fighter or something, Jinx sure as hell isn't as of Act 2, but Isha does definitely find meaning in acting like how Jinx acts, almost as if they view Jinx as a hero. This could be Isha maintaining their inner Fi emotional state by holding onto her idealized version of Jinx, though you could make a case it's Isha trying to cling to her happiest memories, which is all the time she spent with Jinx (more of an Si-dom). Personally, I see them more as Fi-dom, though. As for the question of Se+Ni (ISFP) versus Ne+Si (INFP), Isha again shows signs of both. Isha acts very rashly and to things in their immediate environment and seems dead set on protecting Jinx no matter what, without evaluating other alternatives. This is more typical of Se+Ni, but you could make the case that Isha is an INFP who just hasn't developed any meaningful secondary and tertiary functions, thus acting solely on Fi. On the other hand, as I said earlier, you could see them clinging to the memory of what Jinx means to *them* personally as Si. The last scene of Isha reliving their memories with Jinx in a fantasy-like setting is peak Ne+Si. I think in either case, it's obvious Isha hasn't developed Te yet. They never show any sign of using objective methods for their own goals (aside from basic knowledge on how to use some of Jinx's weapons). Isha isn't thinking about what's best for themselves long term. They're relying mostly on their Fi.
