#and/or that they're SUPPOSED to see being an nothlit that way and assume there's something deeply wrong with anyone who feels differently

Why didn't anyone in the series ask why the yeerks didn't ask Seerow for morph tech in order to escape their parasitic life?

Two things!

Thing 1: There are not only laws but taboos against sharing andalite tech. Ax loves his friends, but he still struggles with telling them about andalite tech when doing so would save their lives. He's less worried about breaking laws than he is about betraying his entire species, and he's genuinely scared that telling humans about andalite tech will lead to a second Yeerk Empire. Presumably most andalites feel the same, judging by their appalled reactions any time one discovers human morphers.

Thing 2: As of andalite-yeerk contact, morphing technology is new, poorly understood, and widely feared. We know that ~30 years later, Elfangor and Arbron still don't understand morphing and have only morphed once apiece — they're terrified when Alloran tells them to morph, and regard Alloran's willingness to morph as an outlier. So way back when Alloran was an aristh under Seerow, we can assume that morphing tech was even more rare and widely feared.

Personally, I headcanon that the two-hour limit wasn't discovered until years into the R&D process, and that even today "two hours" is an estimate based on past nothlitizations. So andalites discover morphing tech, they try it out... and a bunch of them get trapped forever. And they don't know why. And anyone trapped as a prey animal loses their mind in addition to losing their body. And maybe after much trial and (catastrophic) error, they discover that it's safe to stay another shape for 5 minutes. For 10 minutes. For 15. So on, until they get up to ~120 Earth minutes and people start getting trapped again. If that's the case, if 100s of beta testers are nothlits, then no wonder most andalites only morph when they have no choice. No wonder they're baffled and even awed by the Animorphs' casual comfort with morphing.
