It has 2 different common meanings in English -- both too negative to use publicly:
"Rut" as in "Stuck in a Rut" = Going nowhere.
"Rut" = To engage in sexual intercourse. Mostly used for animals. Connotations of brutishness or coarseness.
Even though LLL .COMs have significant value as an asset class, I just can't imagine any English-language company or organization choosing to use this acronym.
You'll need to sell it to someone in a country that primarily speaks another language.
