They are in fact suspicious and using their knife for something nefarious, as confirmed by the end of Chapter 2, and even them looking into the camera is an early hint that they are aware of YOU to the point of knowing exactly where you're watching them from.
Carol's katana(s) is an actual textbook red herring, it's meant to make you think that she's The Knight. But it's still not entirely misleading, she's definitely involved in the conspiracy and probably the actual mastermind, she's just not The Knight.
>Catti's and Jockington's rooms in ch 2Catti doesn't have a room, CattY does. The rooms are just based on the search history of the various townspeople who have used the library, this isn't leading you to anything.
>Asgore's buildup as a scary bad guyPapyrus and other monsters in Snowdin discredit Asgore as a serious evil overlord type long before you meet him. But neither Papyrus or Toriel or anyone else are actually lying about him to mislead you. He has in fact sworn to take your SOUL and will seriously try to kill you to do it, and he's also King Fluffybuns.
>lots of humorous moments based around opposite outcomesThat's just a joke. Not every element of subversion in a story is a "red herring." A red herring is a distraction from something important, a false lead in an investigation.
"Red herring" is also not an inherently bad thing, no story gives you all the answers immediately. There are countless examples where exploring a false lead leads to greater understanding of the story, people just focus on the shitty "lol it was just a coincidence, gotcha!" examples where some shitty hack writer pulls the rug out from under you at the last second because they don't know how to actually tell a story.
