@billy The Le Touquet agreement is a bilateral agremment between France and UK so not in theory related to Brexit but renegotiation could be used as leverage in Brexit talks.
That said, a fuller answer to your original post would be that the French also benefit from the Le Tourquet agreement: the agreement makes it harder for people to apply for refugee / asylum status in the UK, so most likely reduces the steady stream of migrants traipsing through france hoping to get to the UK.
The UK does already pay for much of the border infrastructure in Calais under the terms of the Le Tourquet agreement. Not sure how much but according to Politico it is “hundreds of millions of pounds” between 2003 and 2016.
