You would have to prove that both he, and Sasuke are liars. It's kind of ironic how someone can say he isn't truthful, and then try to lie themselves about him using a device that he didn't even have in his possession until post-Rasengan training. And Konohamaru himself didn't acquire this Ninja Tool, until the mission started, and noted by Mitsuki how it was still in development testing. Which is why they allowed him to use it for the mission, and why it only had one technique in it (Shikamaru's shadow possession technique). Which he later demonstrated how to put the Rasengan inside, and then he destroyed a house on accident. But yeah, it's extremely logical to think he learned to use the device between that interval. Especially when there's no spec of proof on your side instead of ignorance. Much less how those elemental natures got inside the device, which apparently only had one technique, until he put the Rasengan inside. And I'm bloody sure that Konohamaru has not shown Wind, Lightning, or Water elements, or was it stated to have these three as well.

I. Bolt didn't just say he learned 3 elements, he said he learned 3 elements and the shadow bunshin (in the same sentence).

So prove that he's lying there. Can't wait for your excuse.

II. Sasuke said that he applied chakra nature to his Rasengan (which is an elemental nature). If he didn't have access to his elemental natures, which the novel displays as wind, then his sentence would be false. It's most likely his affinity is Wind, or the first element he learned (which is why it is listed first), then Lightning, and lastly, Water.

And fun fact, Boruto said that he learned 'water' recently in the statement. The other two were learned sometime in the past. Even if you were trying to nitpick at the so called KOTE device being used as training, Konohamaru just received for the mission, which was also stated in the Movie in the beginning.

Go figure.
