Not RNG, not dialogue. First try. Let's play spot the difference!
Whether or not changing view model FOV gives you an advantage is arguable, there are benefits and negatives of different FOVs, compare no FOV to a far FOV, or an upside down FOV, all have different pros and cons. The one thing you can objectively say though is that it DOES NOT make you any faster, at all, in any way. I have runs with different FOV, no reason for this run to be taken down lol.
What Mawfeen said. To avoid this when not playing single player, press and hold spacebar before a jump and you won't hang.
Please describe the issue better, don't quite understand what you mean by "makes you go down if your playing not by yourself".
I would rather have faster runs on the current version where you have to do bullshit to work around the bots.
New version out today, 2.1.4.0. Doesn't change anything that would affect runs though.

"-insecure" in launch options fixes all plugin/VAC related errors.
show_addon_metadata shows in the console if you have any addons loaded and what they are, but that wouldn't work for demos since it shows your own addons, I don't think there's any way to see what addons people had from a demo. I don't see anything wrong with demos as long as you use the same timing method as all other runs.
Might as well post something useful on this topic.
0:00 Dark Carnival - When I've used this it doesn't seem to matter where you stand or look.
0:45 Swamp Fever - You have to stand in a fairly specific spot to get them to climb at the right point for the hop, just jump when you see them start to climb and you should be able to make it. It doesn't work if you go too far away from the center of the branch, but you should be able to fit at least 2 people up there. There are other trees that also cause nav errors, but there doesnt seem to be any way onto them with common hops, but maybe with a molotov/grenade launcher jump.
2:16 Hard Rain - This is pretty damn hard, especially without mat_fullbright. Stand on the left side of the trailer so the commons climb at the right point. There does seem to be another nav error spot that you could easily get to with a molotov jump, but when I tested it tanks didn't despawn, but I'll look into it more.
3:18 The Sacrifice - You don't need bile to do this, but it does make it easier. I'm not sure if this actually works though, sometimes you can't press the button, so I need to test this in a normal game. Can't do trick on The Passing due to an invisible wall, and once you're on the bridge everything is blocked until the bridge is down anyway
4:04 No Mercy - Both methods work just as well, I prefer the first one though.
5:03 Death Toll - You need bile for this.
6:02 Dead Air - You have to stand in a specific spot to the the commons to climb at the right point. You have to air strafe to be able to make the jump.
6:44 Blood Harvest - When I was testing it the tanks weren't despawning, but I'm pretty sure they should if they spawn normally. Also because you need a tank to get up there you can only use it to skip the second tank, so not that useful, but if you sit in that spot only smokers can touch you.
7:10 The Parish - Not really useful in a speedrun, but commons can't reach you up there and tanks despawn, although they can still hit you with cars.
I looked into this, apparently it's something that only happens on pinion servers (pinion runs most of the official dedicated L4D2 servers). When cold stream was released this bug was apparently incredibly common, but it is less common now. It doesn't seem to be consistent, I've had it happen in a random game once but have not been able to get it again since. It can happen on every finale, including scavenge finales, making them unbeatable.

Someone's post explaining a consistent way to test for it (haven't tried it myself but I guess it's worth testing):
