Mistakes in your assumption:
1. "only Hindi or English can be used in Tamilnadu HC" - English is the only official language in High courts across India.
2. "water from neighboring states of Karnataka and Kerala is denied by Indian govt" - Indian govt has nothing to do with it. There is no water atleast here in Karnataka you can visit Mysore ill bare your expenses also please come and see for yourself.
3. Jallikattu people here blame the central govt for this but why was the Tamil Nadu state govt sleeping when the law was passed in the center ? Similar thing happen in Karnataka but the state govt immediately passed the law excluding such festivals where buffalo's are used for racing.
Point no 1
Lawmakers can allow another language in a High Court, but so far only four High Courts—in the states of Rajasthan, Bihar, Uttar Pradesh, and Madhya Pradesh—have done so, in each case with Hindi.
The unique allowance made for Hindi in some High Courts smarts for the country’s Tamil-speakers, who have long resented Hindi encroachment from the north. On Sunday, the chief minister of Tamil Nadu
called upon national lawmakers to allow Tamil to be introduced as an official language in the Madras High Court. She argued that “If we are to take the administration of justice genuinely closer to people, then it is absolutely imperative that the local language is used in the High Court, as is already being done by the state government and legislature."
Tamil, India’s fifth most-spoken language, is a Dravidian language with few links to Hindi, an Indo-European language. Unlike other Dravidian languages, Tamil has largely resisted borrowings from Sanskrit, the ancestor of modern north Indian languages. This makes Tamil particularly different from India’s other major languages. These differences are a source of pride. In some ways, the country’s north-south divide is sharpest in Tamil Nadu. Between 1937 and 1986, Tamil-speakers repeatedly protested against the broad adoption of Hindi in India’s central government. Indian states were largely reorganised in 1956 to take account of language. National leaders had planned to keep Hindi and phase out English soon after independence. But pro-Tamil protests catalysed the adoption of the Official Languages (Amendment) Act of 1967, which ensured the survival of the central government’s official bilingualism, a practical recognition that English remained the only workable lingua franca for central government.

Point no 2
for its Kannadiga vote bank, Indian central govt (Congress or BJP) will not implement the SC directive instructing Karnataka to release water to Tamilnadu. Neither will India prosecute Sri Lanka for Killing Tamilandu fishermen nor bother to save them during the Ochi cyclone
