I don't actually use the Emacs grass mode, just Org and Babel and Shells and GRASS. The code below this text works for me, both with and without Babel sessions. There are probably more elegant ways to do this. It would be nice if GRASS could have a "--quiet" option at launch to save the ASCII splash screen. I'm not sure why Org Babel w/ session's doesn't source my ~/.bash_profile. I usually run with ":results verbatim" but sometimes generate Org Tables from GRASS commands, and then use and manipulate them outside of GRASS in other babel blocks in other languages, and then bring results back into GRASS. Also, many things in GRASS take time to run, and Org Babel doesn't officially support asynchronous execution. There are hacks for this, but I often find that I code in Org Babel but execute using an Emacs interface to my shell. This can be the same shell :session accessed by Org Babel. I have various keybindings to send lines and regions to the shell buffer (including appending an audio & visual notification when the commands complete) and then Emacs does not hang, I can continue using it while the GRASS commands run, and I'm alerted when the command finishes and I can send the next chunk to the shell. When development is done, I can tangle everything to a single script and re-run all commands to re-produce the analysis and results using only GRASS and no Emacs, if I so choose (but not if I'm manipulating results in Org but outside of GRASS, as described above).
