Yeah, VSCode plugin doesn’t support .stylelintignore (and it isn’t mentioned in its readme). Try to exclude .js files with ignoreFiles in your stylelint config.

{
  rules: {},
  ignoreFiles: [
    '**/*.js'
  ]
}

- VSCode plugin doesn't support .stylelintignore
+ stylelint API doesn't support `.stylelintignore`
