This should be in the Corolla forums for more help but like with anything, some advice we can still give
If the lower end is siezed due to running low on oil, it is almost always recommended to replace the entire engine just because the lower end may only be the start of some deeper damage, especially if the engine was running without oil for a while.
While running low on oil will not normally turn on the 'oil' light on, the oil light is only a pressure indicator, not level. If there is no oil, well...the light should turn on, but that is usually pass-the-fact the engine is toasted.
I'd recommend a full new engine as a rebuilt will be costly if the damage is significant.
