Are there any hotel shuttle bus service from HKIA to LBP Hotel (Sheung Wan)?

I am afraid that there is no hotel shuttle bus service available. You can take bus line A12 from Airport GTC Station to Western Harbour Crossing Toll Plaza Station. Then, change to bus line 968 to Western Fire Services Street Station, and you can find the hotel. The fare totals HKD 54.5, and the trip takes about 55 minutes.

After taking Airport Express to HK Station, you can take free shuttle bus line H1 to Ibis HK Central and Sheung Wan Hotel, and walk south for about 150 yards to it.

Yes, you can go to Infinitus Plaza at No. 199, Des Voiux Road Central. It is a shopping mall with restaurants. Walk east for about 800 yards from the hotel, and you can find the plaza near Exit E4, MTR Sheung Wan Station. Additionally, there are many restaurants near MTR Sheung Wan Station. Have a try! :)
