The answer to the question is: No. A pokemon is only the type printed at the upper right corner. The exceptions to this were some delta species that have been rotated, but those are very specific.
In the case of Torterra SF, even though he required grass energy, he is still a fighting type pokemon.
Never pay attention to the Attack Cost when trying to understand types. I should always be on the Top Right of the Card. Unless you from last format, they would have them in the middle right.
