Repro Code

class Test {
  set value(val: string) {
    // ...
  }

  get value(): string {
    return 'test';
  }
}

ESLint Config

module.exports = {
  "rules": {
    "@typescript-eslint/class-literal-property-style": "error"
  }
}

tsconfig

{
  "compilerOptions": {
    "strictNullChecks": true,
    "experimentalDecorators": true
  }
}

Expected Result

Should be no errors because the setter exists

Actual Result

Error: Literals should be exposed using readonly fields.

Auto-fix:

class Test {
  set value(val: string) {
    // ...
  }

  readonly value = 'test';
}

Then TypeScript error:
Duplicate identifier 'value'
