if you find a dozen papers using the term, each explaining what they mean by the term, all in agreement with each other, heck, even a hundred of them, then that would *make my point*
So if we find a hundred papers that define a term, it demonstrates that term isn't widely understood or in use in the relevant field?
The term "biologic" clearly
is in widespread use in medicine, biochemistry and pharmacology. I'd agree it might not be well-defined, but it does not refer to intact or deceased multicellular organisms.
Though a contraction of "biological", in those fields it is no longer a synonym for "biological".
Patients, endogenous in-situ tissues are never described as biologic. Physiological systems are biological, not biologic.
Biological specimens in transit are never labelled "biologic specimens" (AFAIK).

There are examples of "biologic" being used as an informal abbreviation of "biological" elsewhere.
My antipathy to Grusch's use of the term is this: If, as he sort of claims, there are aliens or alien remains held by well-resourced concerns in the US, they would be a subject of great interest. Presumably the custodians would want competent (and probably highly-regarded) medical doctors, biochemists etc. to study them. It is highly unlikely these experts would describe the aliens/ cadavers as "biologics", because they would already be familiar with the use of that term
in their professions.
Grusch or perhaps his anonymous informers have chosen to use "biologic", but their use of the term probably isn't from the hypothetical experts who have actually studied the (hypothetical, and IMHO non-existent) aliens/ alien remains.
So where did it originate from?
I
suspect it's a deliberate piece of jargon, in effect a neologism (the users are unfamiliar with the term's meaning in medical science) that Grusch, or an informant, thought sounded better than "alien" or "extraterrestrial". By having a new term (in this context), it creates a superficial impression that they know what they're talking about. And it sounds science-y (hey, it ends in "logic").
Grusch means aliens. In the context, "alien" is widely understood. But we know many past claims of aliens are highly questionable, and in some cases outright hoaxes. Use of a different term might be an attempt to distance Grusch's claims from that baggage.
