Honestly, this is a problem on many SE sites. On main meta, What algorithm does Stack Exchange use to determine if a question may be subjective? tells us that the words Best, Worst, Hardest, You, Your, Favo[u]rite are what triggers the automatic warning. Clearly there could be many questions on many SEs which have titles containing words like "you" and yet are perfectly acceptable questions.
In order to get a site-specific removal of this warning box, we'd have to make a case that Literature specifically is more likely to have OK questions with titles containing these words than other sites. Is this really the case?
It's definitely the case that Literature fields more subjective questions than many of the more hard-science type sites (but that's an argument for not being trigger-happy with the "primarily opinion-based" VTC button, nothing to do with this automatic question warning) and also that this question warning will appear for many perfectly OK questions (but that's not a Literature-specific issue, so it probably belongs as a feature-request on main meta instead). Unfortunately, I don't think either of these is enough to get the automatic subjectivity warning changed for our site.
(But I'd definitely support a feature request on main meta to remove "you" and "your" from the list of trigger words, or indeed a more nuanced request there to make the list of trigger words more customisable on every individual site.)
