I don't believe so.
From what little I can find, the LST class ships never had three engines for propulsion. In the 1950s they were redesigned to have four engines (and then in the 60's, it grew to six engines), but prior to that they all had the two diesel engines.
Here is a list of ships that I looked through on
Nav Source. I tried to get a very wide sample of the different types of LST ships; ranging from LST-1 Class to LST-542 Class.
A few of them had smaller output diesel, but
all of them had
two engines for propulsion. Build start ("laid down") dates in parenthesis.
* LST-10 (August 1942). Originally built as a tank landing ship, it was rebuilt in January 1943 as a repair ship (ARL-1). Both versions had two engines.

* LST-132 (June 1943)
* LST-209 (September 1942)
* LST-230 (June 1943)
* LST-231 (June 1943). Redesigned as the ARL-7 in November 1943. Both versions had two engines.
