All the ones we know of.

And which theoretical gas giants might not contain any? Small ones very close to
a sun?

Really small (eart-sized) ones without a lot of gas. If you don't want
helium to be accessible in every system, postulate a galaxy where not
all systems have gas giants. Lack of gas giants makes it hard to find
helium in meaningful concentrations.
