Looking at a map on https://geology.com/usgs/loihi-seamount/ Loihi is awfully close to the Big Island.
When (if) it rises above the surface, could it connect to the Big Island and not be separate? Kind of like how Mauna Loa joined to Mauna Kea?

Short answer is yes, it might.

Lots of islands are only marginally islands anyhow. Just yesterday I drove from Hadlock, WA; to Indian Island, and on to Marrowstone Island. The first step required a bridge, but only because someone 100 years ago dug a canal across the marshy tidal neck between the mainland and Indian Island. The second step did not, but only because someone dumped enough dirt to create a bit of causeway across another such marshy tidal neck. Were either of them really islands originally? It depended on the time of day.

There are lots of tidal islands that are islands at high tide but peninsulas at low tide, like Mont Saint Michel.

And it will be quite a while before Loihi breaks the surface, so I guess it will be up to our distant descendants to judge.

Maybe the question should be Loihi island or Loihi peninsula or Loihi seamount?

The OP did say 'if' it rises above the surface, acknowledging that Loihi may remain a seamount.
