At least two of the tiny legs were flapping mid-air instead of being locked in vertical position. Also I think their spring excursion should be increased.The speed at touchdown was too high. I think that's what caused the landing gear to fail and possibly also the leak.
unless you invest into a airport fire engine like robot.
They'll have to anyways if they want to do anything beyond engineering tests with those rocket-zeppelins, if they plan to put someone alive inside it will require a super-ready army of robot firefighters to secure the landing in CO2 foam, even when nominal, just in case. But again even that might not be enough to fight a LOX-fueled fire, because as soon LOX evaporates any spark will start a self-sustaining inferno. And those rockets are tall, the crew couldn't like jump and run.
For landing on Earth, there should be better a system to purge the engines with enough force from those gases in a short time.

With all the respect I have for Scott Manley he is quite an self-proclaimed expert... I'd be cautious.
Everyone is speculating. I think there is essentially nothing wrong with that. It was a test flight. Not an accident where a process of truth-seeking would be started. As far as I am aware, SpaceX can say whatever they want about this flight, including lies to discourage competitors's from copying their concept and learning from their mistakes. Right? I think any exchange of information with the FAA is confidential.I'd be cautious.
This method only works if the issue occurs in simpler test conditions. They flew (and did not explode) the Starhoppers looking at these simple conditions. The problems they are having now are because they have an extremely dynamic flight profile, fuel sloshing all about, and they are trying to get reliable shut down and relight on all the engines without using a TEA/TEB system.Yet I think that test conditions need to be simpler in order to isolate the problem.
I'd go back to short straight up / down flights to nail down engine relights and landing legs.
The question is more : can it be done with the tech they have ?
