1-Attsa 'Bout Right.

Actually, anything beyond finger tight is just for anti-rattle conditions, since o-rings are not dependant upon the flange bolts for their sealing integrity anway. Agonizing over trivial things here is not worth the time nor troubles.
BUT the first windmill to jab is to start by using a 1/4" drive ratchet and the correct 6-pointed sockets, use common sense and - adjudicating for some feel - snug is just as good as finger tight - like I said.
However, in a quest to keep ex-NASA engineers from popping up like a bunch of Prairie Dogs and to keep them in their own cubicles until their end-of-shift, the self-aggrandizement specs for most GM A/C Aluminum lines at-of-near-around compressor and assorted fittings, follow the (er) 'following' --- using a freshly calibrated and lubricated with GM Spec Lubricant (GTWL-002.212 j/s) for an Inch/Lb non-torsion bar type torque wrench (GWR-33.01/rev.d) :
Torque the hose assembly at rear of compressor, using new sealing washers.
Tiighten the line to condenser with mounting bolt.
Line at accumulator with mounting bolt.
