Lord knows why they bothered to do it then. No, it's never "illegal" not to Mirandized someone. It merely affects the admissibility of things they might have said unmirandized under certain circumstances.
Yes. The police do not have to read you your Miranda rights at all. The only time they are relevant is at trial. If the State seeks to introduce statements you made while in custody and you were not Mirandized, those statements are inadmissible.

Miranda warnings only apply to statements made after a person is placed in custody. If the state doesn't intend to use any statements then there is no harm.
