The only one i can think of is Valentine - originating from when some is your 'valentine' or date on Valentine's Day.
I love you
There are no other nine letter words that can be made with the letters in 'valentine'; some shorter words that can be made with those letters are:aailalealienaliveanantanteanvilatateaveeateateneaveeelelanelateeliteenlivenentaileveeveneventevilIininaneinletinninnateinventitlalainlanelatelealeanleaveleavenlenientletlielienlinelinenlintlitlivelivennailnaivenaivetenativenavelneatneatenneenetnilninenittailtaletanteatealteeteententietiltiletintinevalevaletvanvanevatveilveinvenalvenialventviavialvievilevineviralvital

Tu es tres belle, ma valentine.

youyou, yourte, yougoslave are French words starting with you.
roses are red, violets are blue
It means Valentine.
The biggest word you can make out of "valentine" is "valentine" itself, which consists of nine letters. Other notable words include "valent," "vital," and "tale." However, none of these words are as long as "valentine."
I don't think the French are missing any of their words.
