Yes, that does remove some of the other potential methods ... but there is one more left... kind of.
Even if a bit more free to me and not actually free , kind of thing.
Net negative in application ... due to limitations in efficiency of devises ... efficiency limitations of the devices which are limited for good reason... not any kind of conspiracy , we just can't make these things that efficient.
Technically the splitting of water under some conditions can be a very mild endothermic chemical reaction ... ie it pulls some of the heat energy out of the ambient heat of it's environment ... the small amount of endothermic energy is energy that could potentially be free to the user sense the user might not have had to pay for that energy ... ultimately it just isn't enough to over come the efficient limitations of even the most efficient devices.
Similar concept of getting more out than you pay for ... many heat pumps that can output more joules of heat energy than the amount of joules of electrical energy the user paid for to run it ... the additional heat beyond the amount of energy the user paid for are not magic ... they still come from somewhere ... but they can be from a source that the user did not have to pay for.
Sadly this is just not a large enough effect even in ideal conditions for the case of H2O / HHO to overcome the limitations on the device efficiencies.
In short the combination round trip of all the 3 steps would combined have to be over about ~83% efficient even under ideal best case endothermic conditions ... which is just too high.
Step #1> Convert electrical energy to chemical energy ... Electrolysis.
Step #2> Convert chemical energy to mechanical energy ... ICE.
Step #3> Convert mechanical energy to electrical energy ... Alternator.
