Yes, he did put his hands up. And Kyle didn't shoot GG while his hands were up.The only video I saw showed him backing away with his hands up and gun pointed up and back, then Rittenhouse shot him.
After GG put his hands up, he then pointed his Glock pistol at Kyle.
GG even had to admit that in his testimony while under cross-examination because it was just undeniable. At first he lied when he said he didn't point his gun at Kyle, and only admitted it after the defense showed a still photo from the video that proved that at the moment GG's bye-cep was transformed into pink mist, GG had his Glock pointed at Kyle.
Like yourself, GG got caught lying his ass off on several occasions.
