Not sure if this is doable, but...

And I don't think it's ever occurred to any of us that a manager might take it upon themselves to proselytize to their residents, so I wouldn't expect that of your SI.  (Although maybe an NPC manager?  Hm.  I'd have to bring it up with the other writers, but I'm kind of inclined to think that the kind of person who would do that isn't the kind of person who'd get recruited.  I mean, I can't imagine an Evangelical Christian would even accept working for Funtom, let alone the multi-pantheon effort; I think a certain flexibility about religion is necessary to be a manager.)

Oh yes, my residents, follow the one true faith!  And ignore all of those beings from the Norse, Greek, and Egyptian pantheons that keep showing up randomly, those are just figments of your imagination.  Also, there's no real polite way of saying this, but you'd be surprised at who Evangelical Christians can convince themselves to do work for.  Try turning on a TV news channel for a few minutes or so, you'll figure it out.

Culturally Jewish?  Yes

Frum?  I was handed sheet music with transliteration for my Bat Mitzvah, and it's been downhill from there.  Although, in my defense, my Bat Mitzvah was on April Fools Day.  The speech had the first paragraph word order scrambled ahead of time (the rest was normal -- and, no, I didn't repeat the first paragraph unscrambled, just picked up as if nothing happened), the buffet was pencils/pens/rubber bands in one dish, Groucho Marx glasses and duck sauce packets in another, and a pair of rubber chickens in another.  And we arranged for the waitstaff to drop the cake (with a multi-page waiver) -- yes, there was a second cake.

If an employee ever dared try to push their faith on anyone, they'd be doing the tailbone-bounce onto the sidewalk!

Time to do this year's rewatch of Haibane Renmei and take notes?

Oh I do hope to see that eventually written up into a story you tell your residents!

The general stuff on religion is of course in our (in-)universe bible, chapter 4 (I recommend the PDF version if you haven't read it yet, especially right now when images aren't loading).  In some sense we're applying similar logic to the anthropic principle, which is why we can have a bible from the perspective of our characters – it's just us trying to figure out what sort of metaphysics could produce the setting that we've made.  And then writing stories based on consequences of that theory.

Yeah, time to do a rewatch, unless the muse has given you something you want to write right now.  It's best to listen to her.  But rewatches when one intends to write are very helpful, because one notices much different things when trying to nail down characters.
