He only did that after Durge absorbed him and it was the only way out. Throughout the rest of the battle Obi-Wan fought using his lightsaber and only used the Force's telekinesis to reflect attacks and grab his Lightsaber back.
That still doesn't change fact the Obi-Wan will use the Force if he deems it necessary against his opponent and he is a practitioner of Force Crush. It's more a testament to his prowess as a lightsaber duelist and physical combatant, plus his reverence for the Force and Jedi philosophy, that he usually only need his martial skill in most engagements. It's not about if Obi-Wan would do it, it's how much does he have to be pushed into it to deem it a needed maneuver.
You're right that he would use force crush if he needs to, but why would he feel that it is necessary to use it against Kakashi? Is there something in Kakashi's arsenal which would push him to use it?
Has Obi-Wan fought a large enemy like the Susano'o before?
Kakashi starts with Perfect Susanoo in the key he's using, which is a 100-120 meters tall, flying tengu avatar made up of blue chakra. It's roughly the size of the Nine Tails, for reference, and he's going to use it to attack. Kamui Shurikens are also pretty lethal and would warrant the use of the force.
Not in main canon as far as I'm aware. In EU? Maybe. The most comparable thing to Susano'o in size in canon would probably be the Zillo Beast. Sources beyond this wiki have more info, but afaik the SW page here is severely outdated.
I think its a stomp match then, since Obi-Wan one shots with every attack meant to hurt him while Kakashi only has some methods of hurting Obi-Wan, which he might be able to avoid with the ForceKakashi starts with Perfect Susanoo in the key he's using, which is a 100-120 meters tall, flying tengu avatar made up of blue chakra.

As far as recent canon, other force sensitives like Kylo Ren were able to slay a Zillo Beast, though he did so after voluntarily letting himself be eaten to kill it from the inside. Don't get me wrong here, this is just a feat of slaying a large monster that is comparable in size to Complete Susanoo (Zillo Beasts are 97 meters tall on average). Vader has also fought the same Zillo Beast that Kylo had slain, the former of whom Obi-wan is comparable to.
He likely would because obi wan’s precog and every force wielder is better than the uchiha’s, plus obi wan will literally sense every jutsu that can and will one shot him and one shot Kakashi and his megazord with class G telekinesis or pluck him out with the force and TK and turn Kakashi into a red paste or just try to force crush Kakashi in his own megazord
