Why I think the Shades do not step in during a lot of situations, when people see the current situation and think they should. (Slight AQ spoilers.)
We already have people below the shades that can peer into the future and see another person's "Fate".
The "current" fate of Teyvat was already written out. They don't step in because they know they don't need to during a situation, because they know how it is going to turn out.
"But what about the Traveler who is a Descender?" You may ask.
Even if a Descender is a "blind spot" in the fate, they can still see everyone elses.
The shades probably knew Dottore's fate was to be defeated at this point in time, so they didn't intervene. Now, if the "Blind Spot" had joined Dottore and had worked with him to change Dottore's fate in some way using their Descender status in conjuncture with Dottore's power to change his fate from defeated to victorious, then things may have changed.
...and then, despite the Traveler not being seen by Teyvat's Fate, everyone else's fate involved would shift and probably alert the Shades to that. If Dottore is victorious, the other's fates would have changed to defeat at that point.
What I'm getting at is that currently, the Shades haven't really intervened in anything because everything between A and Z of Teyvat's current "written" fate has been what they've expected and known already.
The recent Archon Quests just reinforced this belief in me with Columbina's entire ordeal as if she was fated to do all those things to reach that point.
Honestly, I think it's probably the real reason Dottore wanted the Traveler to work with him. It would have been the only way for him to have a chance to break out of his own fate and change it.

Ronova would only interfere if the HP ordered it. The last time she did something by herself, it was implied thst she was punished.
Only blank would be Istaroth.
Their current priority is finding Asmoday, whom they consider a threat if he changes sides.
I don't think they care about what happens in Teyvat and will probably intervene only if the PO's authority is challenged or if another catastrophe like the one in Khaenria with the Abyss were to occur.
As for Descenders, I think that they play a critical role in Teyvat, where they can help enforce fate, as they are the reason why the phopecy in Fontaine was fully triggered or have another say in certain matters that can change the original outcome to something better than the original end. Also, depending on the person, it's possible they could they can take over the entire order built by Celestia
If Dottore was a truly neutral person who did do so many atrocities since the days of his time in Sumeru to join the Fatui because of whatever was his original fate was before the traveler came and brought I down upon him. Hell, if his ego didn't get in his way and straight up asked a descender for help of his original goal, he probably could've succeeded if he had been more humane in his life.
Ppl forget that one of King Deshret followers had to lie to prevent him from killing his own fellow student when he was still in Sumeru
Thats all there is to it
