Many good posts here.
Regular + vitamin pill won't prevent toxins from pesticides entering your system.
To what extent the body can absorb vitamins in pill form is not known, and whether it is actually healthy in these dosages. For example, supplementing with antioxidants over a long time prevents the body from being able to deal with free radicals on its own. This is very hand-wavy but think of it like supplementing with steroids; your nuts cease to work 100% over time, since they don't have to.
Unless you have a deficit, adding more vitamins is not needed and may even be detrimental.
There is a 3rd thing which is often overlooked: Some fruits and veggies have a type of mild natural poison to prevent being eaten from insects. For humans, ingesting some of this poison in small doses is actually healthy. You give the body some stress, and it responds by becoming stronger. I don't know if this differs between organic and non-organic.
