Keep in mind that this is just my personal cannon about this topic, so might very well be completelly wrong when compared with RIOT's stablished lore, but I'll do my best to explain how I see Elemental Magic and its users.
The Lifeblood of Runeterra is just Raw, untamed magic, but thanks to the existence of the Spirit Realms and its inhabitants, not all magic is Raw anymore.
Spirit Gods
The same way that Celestials, Ascended and Aspects do, Spirit Gods have some concepts associated, for example, elements themselves and are these that by "Breathing in" Raw Magic to later expell it now as Elemental Magic attuned to their element, "form" their surroundings.
is the Freljordian Spirit God of Thunder
is the Freljordian Spirit God of Magma
is the Freljordian Spirit God of Ice
is the Shuriman Spirit God of Earth?
Lower Elemental Generator
The Same way that some Spirit Gods can transform Raw magic, some lower spirits also have this ability, but with a WAY inferior output, being these often both lower spirits or incredibly talented magicians.

- Ice
- Light
- Fire
"Energy Taker"
Some lower beings lack this "Elemental Generator" so to speak, but can take the Spiritual Energy or Elemental Magic around them to accomplish feats similar or equal to "Generators"
