Hello @katleya. A "FREESTYLE" collage was introduced by the owner of LMAC Community two years ago. If you are a member and visits their Discord, you will find the information in one of the channels. I'll see if I can locate it again.

I still have some doubts:
a) is it possible to make a free collage? where can I get the basis for it? YES
b) or this free collage can compete in the weekly round of Lets make a Collage? NO

With the FREESTYLE Collages, you have the option not to use the weekly contest image. That's the only difference. You still have to set the beneficiaries.
