Putting aside what the judge may or may not think of himself, the ruling is that actions taken by the Los Angeles government led to this specific situation and because of that, the city is responsible for remedying that situation, at least temporarily, in the near term. The city does not need to be 100% responsible for every contributing factor to have a responsibility here just as a drunk driver is not off the hook because it was also raining when he crashed into someone. Nowhere in the ruling does it claim to solve the broader issue of homelessness or dictate a long-term plan for the city. But it does say that the city can't simply let the situation fester while they noodle for decades on initiatives and broader plans.
