What happens if you don’t boil wort?

Boiling ceases the remaining enzyme activity and fixes the carbohydrate composition of the wort, and hence the dextrin content of the final beer. Dextrins are complex carbohydrates. In the absence of enzyme activity to break them down into simpler sugars, brewers yeast cannot ferment them.

Does LME go bad?

LME tends to get darker with age and some of the flavors get less intense, but it doesn’t really go bad. As long as we are talking about canned LME and not stuff in a plastic container, it will make beer. That’s pretty old for LME. That stuff has a finite shelf life.
