What class/subclass for a 5 year old who is not a strong reader

[Gtdead]

I'm going to say GOO Warlock. He can attack anyone he likes without consideration for range and you can give him a suggestion for 1 or 2 spells to use every day. We aren't trying to milk the class here. A hex and a Tasha's will do, especially if you make them sound fun. He also gets to speak to everyone telepathically. Then every time he gets new spell levels, change his spells into something more interesting. At level 2 for example, he can teleport with misty step and do aoe damage with shatter, or he can keep the old spells if he really likes them.

Spells are good for the imagination and there is an obvious sense of progression to keep things interesting. Champion on the other hand is boring.
