I have a huge Hollyhock growing next to my gas meter up
against the cement foundation of my house (wood floor
house with crawl space). Does this Hollyhock present
an kind of danger to either 1) the gas meter, 2) the gas
pipes, and/or 3) the foundation of my house?

I want to make sure the roots do not affect the gas meter
or its lines and make sure the roots do not crack my foundation.

Unlike pussywillow hollyhock roots are not invasive so I doubt it can
harm anything but itself... now is a good time to relocate your plant
to a more hospitable home away from foundations but you need to dig up
a ball of earth with as much of the tap root as possible, replant
immediately and water well. If you soak the ground well for a day or
two it should dig easily.
