When v.surf.rst is called and no region has been set (i.e. using
g.region), it will fill up all available storage space in my grassdata
directory (~ 130 GB in just a few minutes....).

There's always a region. Please run g.region -p and report results here.

Comment:

I'm sorry. v.surf.rst just does what You have ordered. It would create a
raster with 73665360000 cells, that would take approx. 550 Gb of RAM/disk
(rough calculation without taking into account any compression or
overhead). Next time just check Your region settings before performing any
analysis.
