Linguists call this usage, “the emphatic literally” and the best writers of the past 300 years have used it.

So if it’s good enough for Charlotte Brontë, Jane Austen, Mark Twain, Charles Dickens, William Thackeray, Vladimir Nabokov, and David Foster Wallace, then it’s good enough for me. Literally.

I wouldn't mind that use of the word if there were a different word available that meant "literally literally".
