The allowable overhang for an LVL will depend on the size of the member and the load it supports. Maximum overhangs for various load situations are tabulated in the span tables published by suppliers. Span tables can be found on supplier websites, or can be generated using timber design software. A selection of design programs can be found on our website via this link https://www.woodsolutions.com.au/resources/specifications/span-tables-and-software.

We don't feel the floor joists will need to be replaced, but whether the floorboards will be unserviceable after they dry will depend on the degree of distortion that remains. No doubt the flooring was swollen after being wet for two weeks. Generally flooring flattens out to some extent upon drying, but this can only be assessed when the drying process is completed. If it still looks damp, testing the timber with a moisture meter will determine whether further drying is needed. If you don't have access to a moisture meter they can be hired.
