How do I make a website in 2023 and not get sued?

I'm trying to build websites and I keep hearing many horror stories out of New York about buisnesses being sued vast sums in civil suits all because their websites didn't comply with all the various mandatory legal requirements websites have to abide by now: 1. ADA 2. WCAG 3. Section 508 4. Section 504 5. AODA 6. EN 301 549 7. European Accessibility Act 8. New York Human Rights Laws It seems impossible to even find a single free template that meets one of the requirements fully.

I want to protect myself from web ADA lawsuits by starting off with the most accessible possible HTML template for my site. I cant even find a single public domain template for free that meets WCAG requirements. It feels impossible to be in compliance with all these mandates simultaneously. I have no idea where to begin except perhaps forking the site of W3C's own WCAG page, or perhaps forking the pages of one of these Accessibility-specializing legal firms.(pretty sure they would find out unless I made substantial changs..)

Where does one even begin?
