if you run a Google Page Speed Insight test on the site it displays the opportunities for improvement.
I checked the URL you displayed above.
The mobile LCP element is a 20kb image.
The Desktop LCP element is the Headline – which is pure HTML.
Neither of which would have any noticeable affect on the time they take to load aka LCP time.
The issue is the code being loaded before the page can be rendered.
Looks like you’re using Ezoic – check with them as it is primarily there scripts and the google advert scripts being loaded on the site that are affecting the loading.
