The idea of race as we understand it doesn’t exist in LOTR, just as it didn’t exist during medieval times
Tolkein himself was firmly in a racist society and there's nothing i know of to indicate he acknowledged concepts of race weren't immutable constructs. his contemporaries in history academia would be going off about teutonic races and asiatics---how we think of history in regards to race was constructed post-Tolkien, or at least after he'd written the books.
Beyond this, you can make a convincing argument all that preoccupation with blood & lineage and the reduction of pure pedigree (numenoreans / elves) through miscegenation is clear racial framing.
