You know it's really hard to find a example of the exception where the enemy does something stupid and we make a comeback.
But, a decent one would be the Wukong game I just got out of. The end game stats become skewed / misleading when comebacks do happen. It doesn't show that Mid + Bot lost lane, and that I couldn't go into my jungle without a fed yi there and was 1.0 kda or less for a good portion of the game.

Nautilus(Won lane, camped him all game) 12.50:1 kda, 179 cs
Wukong(Me, Jng) 3.33 kda, 124 cs (bad cs this game, enemy kept getting free invades to eat all my camps)
Yasuo 1.58:1 kda, 169 cs. (Went 0/10 before the recovery and fed the yi)
Corki 2.75 kda, 161 cs. (Lost lane, picked up all the kills on the recovery)
Zilean 1.86 kda, cs doesn't matter. (Gave 3 kills bot lane, rest was teamfights in mid, ult on naut + me is literally what turned around the fights to give us a win)
On the other team
Ezreal 5.0 kda, 225 cs
Yi 3.13 kda, 158 cs
Leona 2.2 kda, 44 cs
Quinn 1.2 kda, 138 cs
At the 20 minute mark the other team had a 8 k gold advantage. At the 24 minute mark they took a greedy teamfight and gave us enough of a foot in the door to win teamfights. At the 30 minute mark they took another greedy teamfight that turned into a straight push down mid into a win.
Legitimately until we started winning those team fights I was feeding (1.0 kda or less). The only one who won lane was Nautilus.
Rankings on both teams incase you're interested.
My team
B3, B4, B3, Unranked(No ranked history), Unranked(Silver 4 last season)
Enemy Team
Unranked(Silver 4 last season), Unranked(Bronze 1 last season), Gold 4(plat 5 last season),Bronze 2, Unranked(Silver 4)
I am 100% sure if I gave up and didn't camp naut's lane and split off for 2 turrets this would of been a loss.
This game doesn't count but all the things I did stupid early (coughs going to yasuo's lane) are perfectly valuable experiences to look through and improve upon.
There are such things as everyone feeding / losing lane and coming back. It's just relatively rare.
If you're playing correctly they could be trying their best to feed hard / be completely useless and still end up with really positive stats.
I mean if Yi would of made a early baron call and just split pushed that game was 100% lost. The only two on our team that could take out yi was a naut + wukong combo or maybe a naut + yasuo combo that would gut us on a teamfight on the other side of the map.
