In 5e D&D, all the life giving spells (be they Clone, Reincarnate, Raise Dead, [True] Resurrection & even Revivify) all require so-called 'expensive' components. This mechanic allows some DM relative control over the otherwise infinite creature life/lives (be they (N)PC or monster). Even with vast fiscal resources, the DM can easily rule that the specific components cannot be found. Example Raise-Resurrect spell-casting situation: "You cannot find the necessary-specific diamond for the spell – they all got used up by previous [royal/powerful/influential] casters down through ages past." Or with Reincarnate: "The exact plants, roots mosses, fungi and resultant unguents required are simply out of season. Sorry." Without these component limitations, low-level spells such as Gentle Repose can effectively ruin all game risk.

In the Monster Manual there are two kinds of casting, be that from 'innate' or 'spell listed' spells. It appears that both systems of monster-magic spells require any &/or all components (?).

A monster not requiring spell components changes the game. Example: should a trio of (otherwise trivial, yet quasi-immortal/'ageless' fae) sea hags gain unlimited access to 'Reincarnate' they would keep increasingly powerful contract-holders down through thousands of years/deaths. If such hags require 'expensive' components, their desperate attempts to generate hundreds of thousands of gold worth of oils & unguents would effectively keeps them in check.

In short: Are there any casters (devas, Ki-rin, nagas, ogre-mage, etc.) with the ability to cast life-giving spells/magic(s) without 'expensive' component cost?
