Answer 1

The correct css property is text-decoration-thickness so your plugin should be:

function ({addUtilities}) {
  const extendLineThrough = {
      '.line-through': {
          'textDecoration': 'line-through',
          'text-decoration-color': 'red',
          'text-decoration-thickness': '4px'
      },
  }
  addUtilities(extendLineThrough)
}

Here's a working version on Tailwind Play.
