I don't understand why "title"s are so partitioning?
Obviously, the PO is accountable for the user stories, but they are not to write them all by themselves.
Let the PO decide what is the next big feature, then pair them with a dev to split into manageable stories.
Such stories will be then smaller and still have to be split in task. But at least, the user story will be small enough to be develop as is.
PO will have the last word about the big picture and the details (user facing) but the means are in dev hands.
