What is illogical? Nothing?

[Anomalocaris]

So if a logical contradiction is "illogical" why do we call it a logical contradiction and not an illogical one?

A statement's logic can be logically inaccurate in the thing it refers to, yes of course.... I am just saying that everything that actually EXISTS in itself must necessarily be logical. Where is this definition any less useful? In fact I think it's more useful because it's more specific and it also makes more sense because we speak of "logical contradictions" and not "illogical contradictions".

Logic pertains to an argument, but an argument concluding in the existence of something that actually does exist is not necessary logical. For example: "Sky is purple, therefore the sun exists" is not logical. Yes, the sun exists. But the sun exists without or without logic. you must present a logical argument for the sun's existence for the sun's existence to actually be logical.
