OP means illeism, which the OED calls a nonce-word (i.e., invented for a single occasion); it is defined as “Excessive use of the pronoun he (either in reference to another person or to oneself in the third person)” and was used only by Coleridge. The parenthesis explains why it is the word OP wants. (It is based on Latin ille ‘that man, he.’)
A google search reveals a significant number of “modern” books which use the term, e.g., Vol. I of the Cambridge Shakespeare Library,
The fact that illeism appears in Troilus after Shakespeare introduced it in Caesar makes it plain that he could readily transfer to a Greek setting something he thought of as characteristically Roman.
