Is there an andúril light with actual rgb aux lights instead of the resistor ones or the single colour ones? If no, is it even possible with the microchip they use? I know its a pretty limited chip.

There are 1515 neopixels iirc. It would fit. I just dont know if the mcus supported by anduril are fast enough.
Unfortunately Neopixels consume too much power, about 1mA quiescent current each, also min Vin is 3.75V according to the datasheet.
The other day I found this small RGB controller, 200uA quiescent current (LEDs off), 300uA LEDs ON, which is much better especially with only one controller for all the aux LEDs.
I don’t really know much about neopixels, what do they need in terms of control, does it have to be a constant signal or can they just stay in a mode until another mode is set? How many MCU pins do they need?
They need one pin for all neopixels. You can daisy chain them. You have to start sending the colours in order from last to first neopixel. Only problem is that it needs to be precise but idk how precise.
1ms shouldn’t be too hard (would just have to have the code to handle it be in the main loop, ideally, rather than an event handler). If it’s significantly under 1ms might be a problem.
