It's not really that there is any delay to it, it's just a part of how the auto-attack mechanic works :P you can disable it in the settings and that will allow you to leave cata instantly if it is causing too many deaths. The way that it works is that your first click on the door basically just cancels the auto-attack feature. It then needs to complete any attack it started before you are able to leave the catacombs, so any click you do while it's performing the last attack won't do anything. It's all pretty straight forward once you get used to the timing of it, you generally want to start mashing the door 1-2 seconds before you need to be out of there to avoid any deaths from it.
Casting and Single handed weapons have a 1 sec delay.
Two Handed weapons (heavy) have a 1.8 sec delay.
You are correct that the click on the door acts as an Action (either 1 sec or 1.8 sec) timer, but you can easily change this by Healing yourself and then click the door, or use a healing action (auto attack) to safely leave the catacomb by clicking the door one or two times.
Using a healing action will help you survive instead of panic clicking the door.
