I will be arriving at LHR by flight. Suppose my flight scheduled arrival at LHR is 1 PM and I book ticket from London by 3 PM and flight arrives late in LHR and I miss the train/bus, do I get some refund from airlines?
No. It's separate tickets, separate companies, and the airline will not reimburse you for costs of a new train ticket, unless there exists a special agreement.

Not directly any missed train.
In Europe you may be entitled to delay compensation based on these rules: https://europa.eu/youreurope/citizens/travel/passenger-rights/air/index_en.htm
However this has nothing to do with missing the train or not, the compensation is based on the amount of delay, not the consequences of it.
