Check the ground for Hex-Lined Snap Trap before getting closer; you can shoot it to destroy it. Stay away from walls Venator can knock you into with Gutshot, and leave Consecrating Grenade's blast area.
Solomon vs Venator
What's giving you trouble?
Full matchup plan
Mid game · Walkers
Use Kingside Knight before Venator traps a teammate, and move them away from nearby walls and traps. The barrier absorbs damage but does not remove Consecrating Grenade's healing reduction.
Late game · Patron
Use solid cover when Venator loads Ira Domini. Wait for him to fire the stakes or for the active timer to expire before exposing yourself; the blessed shots can execute low-health targets. Direct the queen from cover while your team contests the objective.
