It sound's like you are talking the "pig tail" which is connected between the tank and either the first stage or twin stage regulator. The line may be small but it is running tank pressure to the regulator and from there you are dropping to 11" pressure (10lbs if it's a first stage regulator) . If this is the case, it will supply more than enough to your regulator.

From that point forward the line need's to be sized for low pressure. In order to perform this, you would need the total BTU of all the appliances and the length of run to the furthest appliance. From there you can size the system to function properly. It is by far easier to size the line slightly larger now just in case than it is to return and replace it down the road..IMHO

Not long ago I wrote asking about the 1/2" copper feeding my stove.I want to add a dryer and asked if the line going to the 1st appliance would need to be upsized. Some thought so and others thought I may be OK.

I went out to my tank yesterday and found that the supplier has a VERY small tube between the tank and my 1/2" copper feed. It looks like 1/8". Why would they use this? Isn't this restricting my pressure already?

1st and 2nd Stage regulators

are generally used to step down the pressure; the tank pressure varies with the temperature of the vessel and the liquid inside of it. Tha appliances are engineered to operate at a fixed pressure which is much, much, lower than the pressure in the tank. You need to have an LP expert look over your tank and piping to determine what kind of setup you are running before you can determine how much load you may put on the piping.
