I feel like at the scale of an arcology, there isn't really much of a meaningful difference between there being a fire blocking your escape in the massive structure vs, say, fire blocking you escape in a mall. You're either completely surrounded by fire or you're not.

The Grenfell fire was caused by petty corruption. Someone involved in its construction used a cheaper flammable cladding material instead of the (slightly!!) more expensive fire resistant version.

It’s very on-brand for places like Russia and China but clearly western countries are not immune to this kind of thing either.

After the fire there were investigations into towers constructed here in Australia. Many used the cheaper flammable cladding material also. Just like with Grenfell, nothing much was done and nobody went to prison.
