Well, statistically speaking, no. Looking at the chances of stomps, they are no more and no less lopsided than other matches.

So perhaps you're on a bad streak of luck, or, it could be that Turbo feels just all that more harsher, since you take less time to revive and go back to feeling powerless.

There's a lot of weird quirks with statistics tho, and maybe you're in one. For example, the average turbo match length is roughly 23 and a half minutes. That's just what the numbers say. But my personal anecdote as someone who ALWAYS plays party turbo? It's that games have a coin flip chance of having Tier 5 items, corroborated bu the actual match length numbers in game. Party games being way longer is one such quirk (and is true on both rank and unranked).
