Should I correct a single trivial typo in a submitted manuscript after they rejected the first submission for having too many typos?
I'm assuming you sent it for another round of review. Wait for their comments. Provided that you really did remove most of the typos in your manuscript, and otherwise followed the reviewers' recommendations, I really doubt this will be an issue.

If, however, you sent the camera ready version to the journal, then you should consider contacting the editor and ask if you could re-submit a corrected version.
