Johhny isn't Bi, it's hinted a bit w/Daken(who has pheromones and is a master seducer) so I think it's a no.
I think it would be a cool thing though, only downside and is the Spidertorch fandom will light up and be more aggressive than ever.I hate that ship because of it's stans/fans, and I do see Torch as Bi I've had people say slurs/threats I can't repeat here w/out getting banned on why Peter isn't straight.Ofc they are just projecting, and call it queerbaiting.
A bit unrelated but did anyone see the Rhodey/Carol MCU ship drama go down? More reason to stay away from shippers
