I managed to get a whole bunch of glitched items at once without crashing while attempting to improve the TAS. Posting here in case it might lead to something.
Uploading for now as "proof of concept" beating the first boss without healing, by skipping its turn and advancing the RNG using "Flippendo" spell which costs 0 MP (but lots of frames).
Now at least optimized input-wise.

I take a slight detour to obtain 56,448 sickles so I would be set for the rest of the run. There's actually ~4 other NPCs that when talked to also triggers this iirc.
I can't override the knight boss with the frog, so I fought it at the lake instead. Getting the sickles seems to have reduced the XP I obtained, but it's still enough to reach level 78.
Terrible RNG with the snake spawn; encountering one earlier or later seems to not drop the fangs, or have more than 1 snake.
I take all the ingredients for Herblore outside due to unable to deathwarp out of classrooms because of my 665 HP.
I can't seem to manipulate a critical hit at the ogre; if possible it'd reduce the fight by 1-2 turns (from current 4)
I sell the pumpkins so I'd scroll less for the chocolates
I had to buy 150 chocolate frogs just to get enough cards to card glitch 4 times; After consideration I don't believe it's worth using the cards to death warp to and out of the restricted section.
I'm not sure if buying the chocolate frogs after getting the curse book is optimal or not, but the alternative was either Gringots revisited or getting the presents, and those 2 would result in an extra menu opening because I had to learn Mucus ad Naseum.
I tried, but I can't seem to OHKO the giant rat at level 78.
Edit: It's 71 frames faster in this case to kill the 2 small rats first then 2HKO the giant one then.
Thanks to several people (gand988, SuperMonkeypotato, psirockin123 and more) at the SDA thread for that trophy room skip among other tricks!
I opened the items menu instead of equip due to less lag for the troll skip. It shouldn't really matter for a real time run however, due to the savings being less than a second.
