You only risk getting banned if you use the trainer online. There is no risk if you use it offline.
I don't know. I see VAC fires even in single player. Check the console.
"VAC secure mode is activated."
Somehow I find it illogical for vac to start up in solo play but apparently it dose.
This has probably something to do with the fact that the single player mode is actually the same thing as multilayer but without the master server/network connection initialized.

What is the likelihood of this trainer causing a vac ban on a SP campaign. I really don't want to lose my steam games and am more than a little paranoid.
My advice would be to close the game before moving to multiplayer. Rather than going from singleplayer using a trainer to the MP mode. Closing the game fully and restarting will ensure that the game's memory is clean from alterations. A local, non-VAC game should be absolutely fine. Start your steam client in offline mode if you have any doubts. Other than that, just the obvious really, such as don't let anyone else use your account.
If you are that scared, just restart your steam in offline mode. And play singleplayer.
"The VAC will only send cheater reports during an MP game."
Yes and as such... like there are VAC servers and non-vac servers. But since L4D2 is Matchmaking not a 'choose a server' type, every servers might have VAC on.

There is a choose-a-server element in the L4D games. Hit the tilde key to open the console, and type "openserverbrowser". I'm not sure if there is a VAC option, but I wouldn't recommend using the trainer here either. Anyone can take a video of you using the trainer (firing more shots than a clip holds, having no weapon spread) and send it to Valve with a complaint. That can get you banned as well, and anyone looking to forward their community has no problem with banning cheaters.
