Is there a cream etc that can get rid of the bad odor of a toe infection?

See a podiatrist: If you have an odor then you need an antibiotic to kill the bacteria.

If you have an : Infection ...You need to get rid of the infection....Hopefully you are under the care of a podiatrist, if not see one. You may need a partial nail avulstion or drainage of an abcess. Or an oral antibiotic. Once the infection is clearing up the smell should go away. Usually, when smell is that strong, the infection is likely to be more severe.
