In the world of licensed contracting you absolutely do. If you provide a contractor specifications that result in a code violation, they have to tell you no. If they don't tell you no then you, the non expert, are reasonable to assume what you asked for is acceptable. If they actually build the thing, they are liable for the violation of code.
The last thing we need is to hand out more excuses to evade accountability and responsibility for making the world worse.

I'm definitely not advocating that. I'm more advocating that you can't leave all this to someone else entirely. Even if you pay someone for a turn-key custom website and make sure it's accessible, there's no guarantee it still meets standards a year from now, just as if you pay a contractor to build a ramp for you that perfectly meets standards. Things change, and people need to pay attention to the things that matter to them to make sure they follow the law. Whether that's occasionally checking it yourself or paying someone else to do so (and thus ensuring it happens), it still needs to happen.
At the same time, if Google is advertising Recaptcha as accessible and it's not really, then they need to be held accountable for that, because that has a real impact on huge swaths of the internet, and especially for sites that try to do the right thing and find out Google has screwed them.
