that part is actually specified as "do not remove". So although it is technically "removable", I do not know if there is a replacement part available. SUDCO might be able to help you out if you call them up.
Hi there one trick to try is to heat up the venturi a little bit that will make it expand and the pilot might just come out a bit easier.
Wait for the wife to go out and then bung it in the oven for a short time at a low heat ;) .
I have done that with other stuck treads and it's worked every time,
I would make sure that the carb is very clean first.
