Not as far as I know. The European market was very inconsistent when it came to video, and one of the reasons was that we use 50Hz instead of 60Hz here. And that meant that all games were capped at max. 50fps instead of the 60fps that other regions had. This also affected other 30fps games that normally ran at 29fps in their European release or even movies, films and TV Shows that ran at 23fps in Europe instead of the standard 24fps. There were tricks developers used in order to run their games as smooth as their NTSC counterparts in PAL consoles, in spite of the inferior framerate. But in the instances where they didn't, you saw a 16% slowdown (Sonic I'm looking at you). Luckily for us, newer TVs released in Europe were compatible with both 50Hz and 60Hz, and by the 2000s many PAL games started taking advantage of it, by having selection screens for 50/60Hz appearing before starting the game. So going back at your question, the Gamecube had many games that were compatible with PAL60, which is 480i at 60fps in a PAL colour space. Gamecube games that didn't support PAL60 but ran at 60fps in other regions much likely ran at 576i/50fps in their PAL release, and those that ran at 30fps, ran either at 576i/29fps or 576i/30fps here.
