BTW, what is the new word to use when one literally means literally?

There is none. The word has been misused to the point of ambiguity being an accepted part of its definition, and we are all worse off for it. The language is now less expressive, and you need to use more words to add context and remove ambiguity when you really do mean "literally" in the literal sense.

‘Actually’ is what I’ve heard most often.

Use literally. It still means literally. Language has all kinds of things like sarcasm, exaggeration, and metaphor that change the way a sentence should be interpreted, but the meaning of each word remains the same.

You add “quite” before “literally”.

Just prefix the sentence with “literally literally (not literally literally)”

Gen Z uses the very awkward "unironically".

that too, will often get used ironically
