Solomon as a biblical figure is never mentioned in the 'Odes of Solomon', so the reference may be to the word 'peace' and have no connection to the biblical figure named Solomon. But it's possible he was a fiction who could be used in a wide variety of ways. Note the key early Christian text called the 'Wisdom of Solomon'.

These were theological texts, not history books. Note- Archaeologists can't find anything like a Solomonic kingdom, so it appears all that was a biblical fiction. This is just facts.
