Mom wont stop ai generating a trip (help plan me plan a proper route)

As title says mom wont stop going to chatgpt for plans which then fall through as we cant actually get anywhere :/

We're in the bottom of france driving and will go into Italy Switzerland austria Belgium and Germany before going back into the tip of france and into england

What sights in each country do you guys think are good and what should we avoid.

With those countries what cities towns and sights would you suggest? About €150 a day in budget and would like to see some nice towns with things to do, not particularly interested in 500 of the same looking churches and cathedrals unless they're genuinely gigantic and worth looking at.
