Particularly if the sauce includes unstrained organic bits such as garlic or onions, or includes oils - botulism (odorless, tasteless) can be a non-zero risk.
At some point, that crusty $5 bottle of hot sauce you found in the back of the fridge should just get tossed out instead of taking the risk.
Tabasco in particular isn't just vinegar-based, it's nearly entirely vinegar. Its ingredients list is vinegar, salt and crushed peppers that are then strained before bottling. It is a very inhospitable environment for botulism - or anything else.
Many other types of hot sauces contain oils and/or are not strained of organic matter and/or contain blended organic matter. Such as all of your thicker or chunkier sauces for the most part[1] (which happen to be my favorites). Those should be kept in the fridge and you should discard after some time just to be on the safe side.
