It's a shame this loses one of the most useful aspects of LLM un-minifying - making sure it's actually how a person would write it. E.g. GPT-4o directly gives the exact same code (+contextual comments) with the exception of writing the for loop in the example in a natural way:

    for (var index = 0; index < inputLength; index += chunkSize) {

Comparing the ASTs is useful though. Perhaps there's a way to combine the approaches - have the LLM convert, compare the ASTs, have the LLM explain the practical differences (if any) in context of the actual implementation and give it a chance to make any changes "more correct". Still not guaranteed to be perfect but significantly more "natural" resulting code.

Depends on how many tokens you want to spend.

Making the code, fully commenting it and also giving an example after that might cost three times as much
