What if Gotenks's ssj3 didn't run out?

[KyuubiAhri]

would gotenks have killed Super buu?

Depends on how you view Super Buu's words.
-If you think Super Buu could have performed better but was just stalling,
he wouldn't have been killed. Gohan arrives and nothing changes.
-If you believe Super Buu was done for at that moment, everything is back
to normal, except Goku and Vegeta remain dead.

Everything revolving around the scene implies Gotenks could've finished the job if he'd taken it more seriously, so this means Boo dies, Goku doesn't get revived (unless Elder Kaioshin offers to do so and Goku obliges) and no Good Boo or Oob. This offers a solid end for the series unless taking Super into account.

With Super, it depends whether or not Goku stays dead. If he does, then nobody's there to stop Beerus destroying Earth. If he is alive, then Beerus would just get bored after enjoying the festivites, with Goku later entering for a rematch with far less tension than before. This doesn't really change much in regard to Super, other than that without the MY BULMA!! rage boost, Vegeta would probably be lagging behind Galu to a greater degree.

I don't see why that would be the case. Beerus would still be capable of meeting with Goku, plus the Oracle Fish's prophecy and Beerus' foresight are dubious at best.

 

[Let's Go Fearless!]

And Gotenks wouldn't still get the job done, and Buu will just absorbed him until Gohan arrives.

Oracle Fish didn't make that prophecy in Trunkses timeline.
