This has probably been said many times, but Smite really should be immediately available as a summoner spell. You shouldn't be forced to play games without a jungler.
Riot recognizes jungle as an official role, one that is required on every team, so why are teams forced to play without one for such incredible lengths of time? Being in a position where your team is incapable of having a jungle vs a team with at least one player with smite is very imbalanced and anti-fun. It's a massive disadvantage. Seriously, help your new players get onboarded to how the game is played sooner, have less frustrating matches, and maybe even let them try the role themselves.
