No, it’s not too late. I live north of you and, for the same reasons, have yet to “sow my maters.” Since tomatoes come in many sizes, shapes & varieties (and colors), just look for those with a shorter growth time. You can also cheat a little & buy tomatoes already in a pot. You might try Summer Girl, Bloody Butcher (gotta love that name!) or one of Burpee’s Samplers. (Note: I grew up on a farm & we always ordered seeds from Burpee, I get no funds from them for mentioning them or linking them…though I’m open to negotiating if they’d like to reach out! LOL).
