Please read the eligibility criteria below

• A candidate seeking admissions in the three year LBB programme should be a graduate from any recognised university with atleast 45% aggregate marks. Candidates belonging to SC/ST categories must have secured atleast 40% aggregate marks in their qualifying degree.
• And the candidates seeking admission in the five year integrated programme, should have passed their 10+2 intermediate degree with atleast 40% aggregate marks

For the 5 year integrated programme you need to have atleast 40% marks in aggregate in your class 12/Inter. Since you have not done inter/12th you are not eligible.

For the 3 year LBB programme you need a minimum of 45% general category and 40% reserved category plus you need to have passed class 12/inter too. With your percentage as well as not having done Inter/class 12 I'm afraid you are not eligible for TS LAWCET.
